mutantC is a Raspberry Pi UMPC. An open platform device to use any serious professional work and create your ecosystem of automation. It is fully Open-Source hardware. So you can hack it as you wish. Make your expansion-card like GPS, Radio etc and attach them. You can access all the ports of the Pi. The back part is attached with 4 screws. It can hold a 4" or 3.5" touch screen. Also have a 52 button physical keyboard. It doesn't need any custom OS, you can use plain Raspberry Pi OS and install the LCD driver, that's it. So little parts needed to make one. The priciest thing is the LCD and Pi.Please shear the link to all your friends .Project LinksYouTube Project Website Discord Matrix TwitterBuild Guide1. Order the parts from online, here is the full Parts list.2. Order the 3D printed parts, you need to print 4 parts, here is the parts files. You can Order them from PCBWay 3D printing service.3. Order the PCBs, there is 3 PCB you need, here is the files you need to order. You can also order the PCBs from PCBWay PCB prototype service. That way you can get the 3D parts and PCB fast within minimum days and save shipping costs.Now solder the parts and flash the firmware from here. Now flash a SD card with Raspberry Pi OS and install the LCD driver from the place you brought the LCD module.That's it you got your fully working mutantC v4. If you want to try out some Expansion Boards you can see some of them from here, there is 6 of them currently.https://www.youtube.com/channel/UCbU1bjAwaDnZZvXIBHzUXuQhttps://discord.gg/9nHn6YNr

mutantC v3 - Display PCB

https://gitlab.com/mutantC https://www.reddit.com/r/mutantC/https://matrix.to/#/!dtgavqeIZQuecenMeX:matrix.org.There is 3 PCB you need, One is this and other 2 are below, Add this and other 2 in cart all togather.mutantC_v3_ThumbStick_PCBmutantC_v3_Display_PCB First take a look at this in 3D using AutoDesk Fusion 360 Online her?e.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. Youtube channel.Here is the Project website.Project files in Gitlab .So make yours and help us to make a Community around it.https://gitlab.com/mutantChttps://www.pcbway.com/project/shareproject/mutantC_v3___Display_PCB.html
