“A Raspberry-pi handheld platform with a physical keyboard, Display and Expansion header for custom boards (Like Arduino Shield).
mutantC_V3 is successor of mutantC_V1 and V2. Check out mutantC_V1 and mutantC_V2.
First take a look at this in 3D using AutoDesk Fusion 360 Online here.
There are some key features.
Have RTC & buzzer.
Supports v2 Add-ons.
A track point to have mouse support with left, right buttons.
Gyro support using MPU6050 module & presure, temp and humidity support usin BME280 module.
Able to turn of modules, Display, Add-ons using keyboard button.
Full poweroff using OS and keyboard key.
12 pin docking port beside Pi USB ports with UART, I2C, Charging and GPIO.
3D parts are more solid and reduce supports when printing.
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 acessible from outside.
It is fully open-source hardware. So you can Hack it as you wish.You can make your expansion-card like gps, Radio etc and attach with it.
You can use any Raspberry-pi form factor like Asus Tinker Board S / PINE H64 Model B/ Banana Pi BPI-M4B etc. You can use Raspberry-pi zero to 4.
You can access all the ports of the pi and the back part is attached with 4 screw.
It can hold a 4” or 3.5” touch screen. Also have a physical keyboard attached via USB.
18650 battery with charge and discharge protraction .
You can use Littlevgl make UI that don’t need a OS form here.
It don’t need any custom image of Raspbian. You can use vanilla Raspbian and install the LCD driver, that’s it.
So little parts needed to make one. See the parts_list .
You can use C Suite Application suite made more touch based device in this. This apps are suitable for small screens. See the C Suite.
Added Adafruit STEMMA QT and SparkFun qwiic connector.”
