MAKERphone 2.0 on Kickstarter: A No-Soldering 4G Phone You Build and Code With AI
A kid's first phone is usually a compromise. Not between good and better. Between boring and unsupervised: a locked-down flip phone that bores them by lunchtime, or a hand-me-down smartphone that quietly hands over social media and an infinite feed. Neither one teaches anything about what's actually inside the thing in their pocket. The MAKERphone 2.0 on Kickstarter starts from a different question: what if the first phone was one they built themselves, then taught to do things no app store offers?
The CircuitMess MAKERphone 2.0 has raised $272,928 from 1,563 backers against a $30,000 goal, with 25 days remaining. The company has shipped over 300,000 kits to 100+ countries since 2017, with press coverage that includes WIRED and TechCrunch.
Quick Verdict
Our verdict: 9.1/10
Who Is It For?
MAKERphone 2.0 suits the kid who takes apart the remote to see how it works, and the parent who wants a first phone that teaches instead of distracting. It also fits the maker who wants a MAKERphone kit with a modular port, not a sealed case, and the teacher who needs a Classroom Pack sized for a whole room.
Main Strengths
No soldering iron needed: parts click, screw, and plug together in about two hours, replacing the 2018 original's seven hours of soldering, on an upgraded ESP32-S3 with more onboard memory.
Real 4G LTE Cat-1 hardware with 2G fallback and a nano-SIM handles actual calls and real SMS with media attachments straight out of the build.
VibeBoy turns a plain-English description into a running app or game, then teaches Python and C++ as skill grows across four tiers, Pixel Rookie to Vibe Coder.
Six UMAX modules, including a camera and a DIY perf board, are auto-detected on plug-in and added straight to the phone's menu.
MAKERband, a buildable Bluetooth smartwatch coded through the same VibeBoy workflow, pairs with the phone and with iOS or Android, and bundles in at a discount on several tiers.
Main Limitations
The campaign material doesn't mention CE, FCC, or other regional certification for the cellular modem, which matters for backers using it as a primary phone abroad.
VibeBoy Pro's unlimited AI usage is guaranteed for three months only, and the campaign doesn't specify what limits or costs apply afterward.
Shipping is charged separately after the campaign, and CircuitMess isn't scheduled to begin fulfillment until August 2027, about ten months after this campaign ends in October.
Is the MAKERphone 2.0 Worth Backing?
The MAKERphone 2.0 earns a strong recommendation for the parent who wants a first phone that teaches instead of distracting, and for the maker who wants a 4G handset with no locked doors. It's a pass for anyone who wants finished hardware with zero build time, since CircuitMess's record of 37 shipped products since 2017 doesn't shorten the two-hour assembly. Between the no-soldering build, the real 4G radio, and VibeBoy's coding ladder, the MAKERphone 2.0 on Kickstarter earns it on substance rather than novelty.
MAKERphone 2.0 Price on Kickstarter
The $129 MAKERphone kit tier is the one to start with: a 24% discount off the $169 post-campaign price, including one phone and three months of free VibeBoy Pro. Backers who also want the MAKERband smartwatch should take the $189 MAKERPACK instead, bundling both builds into one box. Classrooms get a dedicated Classroom Pack at $1,999 for ten of each, about $200 per student and a 33% discount against retail.
The value case here isn't the 24% discount so much as what's included: real 4G hardware, a modular expansion port, and an AI coding studio that scales from a first plain-English project to hand-written C++. The Classroom Pack applies the same logic at scale, packaging ten phones, ten bands, and ten expansion module packs into one purchase for a classroom. The MAKERphone 2.0 on Kickstarter starts at $129.
What Is the MAKERphone 2.0 and What Problem Does It Solve?
MAKERphone 2.0: A Real 4G Phone You Build, Then Program With AI
CircuitMess MAKERphone 2.0 is a real 4G mobile phone that ships disassembled, meant to be built by the person who will use it rather than a factory-sealed unit. Once assembled, it makes calls, sends SMS with media attachments, and runs a phone suite of contacts, calendar, notes, and a music player, on top of hardware the builder installed themselves. VibeBoy, CircuitMess's AI-assisted coding studio, then lets that same builder describe new apps or games in plain English and watch them run on the phone they just built.
The hardware runs on an ESP32-S3 processor with 4MB of flash and 4MB of PSRAM, more memory than the original MAKERphone carried, paired with a 1.77-inch color display, a 12-key numpad, and a joystick. CircuitMess admits its delivery dates slip, since "hardware is hard," as the campaign itself puts it, but says every one of its five completed Kickstarters has shipped, with the sixth, Butter Bot, shipping now, a track record that matters for a company asking people to prepay for a phone that still needs assembling.
Why a Kid's First Phone Became an All-or-Nothing Decision
A basic phone keeps the distractions away, but gives a curious kid nothing to explore. A smartphone adds apps, social feeds, and an app store from day one, whether anyone in the house is ready for that or not. Parents end up choosing between the boring option and the unsupervised one.
MAKERphone 2.0 sidesteps the choice by making the phone the project instead of the reward. A kid who spends two hours assembling a real 4G handset ends up understanding, screw by screw, what's actually inside one, and any new app on it comes from VibeBoy or from code written by hand, since there's no store on the device to download one from. The result is a phone that can call and text without opening a door to social media or an infinite feed, because that door was never built.
MAKERphone 2.0 Key Features and Specs: No-Solder Build, AI-Assisted Coding, and Modular Expansion
No Soldering, Real 4G: The Build That Replaces the 2018 Original's Iron
The original 2018 MAKERphone took about seven hours of soldering to build, and CircuitMess has said as much itself, thanking those backers for their patience. The CircuitMess MAKERphone 2.0 needs none of that: every part clicks, screws, or plugs into place, and CircuitMess estimates about two hours of assembly using its illustrated LEGO-style manual and video guides.
The same ESP32-S3 processor runs the whole line, and the phone connects on real 4G LTE Cat-1 with 2G fallback in place of the 2G-by-default radio the first MAKERphone shipped with. Any carrier's nano-SIM works, putting real calls and texts on real cell towers instead of a simulated dial pad.
VibeBoy's Four-Rung Ladder: From Plain-English Prompts to Handwritten C++
VibeBoy is CircuitMess's AI-assisted coding studio, and it's built around four skill tiers instead of one fixed skill level. Pixel Rookie, for ages 9 and up, starts with describing an idea in plain English and watching it run on the phone; Signal Hacker moves into reading and editing the Python code VibeBoy writes; Modder has backers writing Python and C++ from a blank file; Vibe Coder directs the full AI workflow like a senior engineer directing a team.
Finished games and apps can be shared with other backers and remixed, so the library grows from what the community builds, with no app store in the middle deciding what's available. Every backer gets VibeBoy free for life, with three months of VibeBoy Pro and unlimited AI usage included.
The UMAX Port and Six Plug-In Modules
The UMAX port turns the phone into a small expandable platform. Six modules are available at launch: a camera for retro-style photos and video, a bigger speaker, a bright flashlight, an environment sensor for temperature and humidity, an infrared module for controlling TVs and other IR devices, and a DIY perf board for backers who want to solder their own circuits into the phone.
Plugging a module in triggers a pop-up on the phone and adds its app to the menu automatically, so there's no manual pairing step to walk a young builder through. The Expansion Module Pack is a separate $39 add-on for backers who didn't pledge for one of the tiers that already includes it.
MAKERband: A Second Buildable Device That Pairs Over Bluetooth
MAKERband is a second build: a programmable smartwatch on an ESP32-C3 chip with a 0.96-inch color display, four buttons, and Bluetooth 5.0. It ships with 15 watchfaces out of the box, and backers can code their own through VibeBoy the same way they code apps for the phone.
Paired over Bluetooth, it syncs phone notifications, controls music playback and the phone's camera shutter, and carries five mini-games of its own. It also pairs directly with iOS and Android, so it works as a standalone watch even away from the MAKERphone.
Battery, Storage, and the Full Phone Suite
The 1000mAh battery charges over USB-C, the same cable used to program the phone during builds, and there's a microSD slot for music, photos, and video the builder wants to carry along. Beyond calls and texts, the phone runs a full suite: a music player with playlists, a gallery, a calendar, notes, and a file explorer.
Without a SIM, the phone still runs games, music, coding, and the UMAX modules over WiFi and USB, and WiFi also handles firmware updates and syncing with VibeBoy. There's no browser or app store on the device; a real-time clock and small decorative LEDs round out the spec sheet, and warranty on the finished build runs two years.
Should You Back the MAKERphone 2.0 on Kickstarter?
MAKERphone 2.0 reframes a kid's first phone as a build project with real stakes, not a locked-down accessory handed over on a birthday.
This isn't a prototype pitch: CircuitMess says the hardware on this page is final production, with the software already in its last polish before mass production begins. A parent still gets a phone with no social feed and no app store to fight about, and a classroom gets kits that scale a coding curriculum instead of a stack of empty afternoons.
CircuitMess MAKERphone 2.0 has raised more than $2.2 million across six Kickstarter campaigns since 2017. At $129 against a $169 post-campaign price, the MAKERphone 2.0 on Kickstarter is currently funding with 25 days remaining.
In 2018, the original MAKERphone required about seven hours of soldering and, by CircuitMess's account, at least one burned finger. This one asks for a screwdriver and two hours, and hands back the same thing that mattered the first time: a phone a kid understands, because they built it.
FAQ about the MAKERphone 2.0 on Kickstarter
Do I need a SIM card to use the MAKERphone 2.0?
Yes, for calls and texts: a standard nano-SIM from any carrier works, prepaid included. Without one, the MAKERphone kit still runs everything else over WiFi and USB, including games, music, coding in VibeBoy, and the UMAX modules.
Does the MAKERphone 2.0 have WiFi and Bluetooth?
Yes, both are built in with no module required. WiFi handles firmware updates and syncing with VibeBoy, while Bluetooth pairs the phone with MAKERband and other accessories.
Can my child browse the internet or use social media on it?
No, and CircuitMess built it that way on purpose. There's no browser, no app store, and no social media, only calls, texts, and whatever apps get written for it, in VibeBoy or by hand. If an app doesn't exist yet, the idea is to build it.
Is VibeBoy's AI required, or can the MAKERphone 2.0 be coded by hand?
It's optional. The phone ships with its own firmware, a classic phone suite, and built-in games with no AI involved. VibeBoy runs on a computer and only touches the phone when a project gets sent to it, so writing every line of Python or C++ by hand is equally supported.
How long does the MAKERphone 2.0's battery last?
CircuitMess doesn't publish a runtime figure, only the hardware: a 1,000 mAh battery charged over USB-C. The battery goes in by hand during assembly, so backers already know how to swap it themselves without sending the phone in for service.
