This neat little device is an open source mobile phone that you can build yourself.
Besides that, MAKERphone is also an educational device shaped like a mobile phone compatible with all mobile networks.
Its purpose: to motivate people to explore, learn and create something new in a fun and interesting way.
PLEASE NOTE: We sell this kit in Elegant Black only! The other colors shown are not presently available!
Based on our experience, an 11-year-old kid should be able to assemble a Ringo kit with a tiny bit of help from an adult. Estimated build time: 5 hours.
Building the Ringo kit is just the beginning.
After that, you'll spend numerous hours creating your own games and apps and experimenting with hardware.
You'll need some basic tools and equipment for assembling your Ringo:
Ringo is based on Arduino-compatible ESP32 microcontroller. Therefore, it's compatible with lots of hardware expansion modules.
Ringo was meant to be hacked.
Ringo is fully customizable.
A dedicated graphical code editor similar to Scratch or Code.org.
Getting started with coding was never easier!
Circuit OS is our custom-made operating system built on top of FreeRTOS. Currently it only works on our CircuitMess Ringo DIY mobile phone, but we plan to adapt it for all of our current and future products.
YES, we love Arduino.
Ringo is based on Arduino-compatible ESP32 microcontroller.
Therefore, it can be programmed in Arduino IDE (based on C/C++) – the most popular programming environment for makers.
