mutantC_V3 All the info you need to make one
New Features in mutantC_V3 with all the blessing from V2
mutantC_V3 is successor of mutantC_V2 and with more features.
This improves big parts and brings new improvements like .
- Have RTC & buzzer.
- Supports all the v2 Add-ons, see all from HERE.
- A track point to have mouse support with left, right buttons.
- Gyro support using MPU6050 module & pressure, temp and humidity support using BME280 module.
- Able to turn of modules, Display, Add-ons using keyboard button.
- Full power off using OS and keyboard key.
- 12 pin docking port beside Pi USB ports with UART, I2C, Charging and GPIO.
- Able to read battery voltage using Pro Micro.
- 2 LED's connected to Pro Micro with PWM support and 1 connected Pi.
- Move the Stema/Qt I2c connector bottom so it is accessible from outside.
- 18650 battery with charge and discharge protraction .
- Improvements to Stop position for sliding mechanism.
- 5 row, 56 key customizable keyboard .
- New 2 shoulder button for navigation.
- Reduce keyboard power usage .
- Have Adafruit STEMMA QT and SparkFun qwiic connector.
Getting started
CheckOut mutantC_V4 as it is successor of this from here.
Take a look at this in 3D using AutoDesk Fusion 360 Online.
A Raspberry-pi handheld platform with a physical keyboard, Display and Expansion header for add-on boards (Like Arduino Shield).
Here we will discuss what you need to build one. This device is very easy to make, you don't need lots of tools and parts.
No codding skill is needed. just basic stuff like upload a code to Arduino, little skill in Linux CMD line to install the driver. Little soldering skill that's all.
