mutantC v3 - modular and powerful handheld PC

Description

You can make your expansion-card like GPS, Radio etc and attach them. 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. It don't need any custom image of Raspbian. You can use vanilla Raspbian and install the LCD driver, that's it.

This device can controll your ROBOTIES, QUADCOPTER use for HOME AUTOMATION, LONG DISTANCE MESSAGING and many more with one device. Also deploy bunch of mutantC in the field and use for managing your big projects, use the DOCKING port to collect data from all of them easily.

Details

Checkout the poject website from here.

A Raspberry-pi handheld platform with a physical keyboard, Display and Expansion header for custom baords (Like Ardinuo Shield).

It is fully open-source hardware with MIT. So you can modify or hack it as you wish.

It is platform like Arduino. You can make your expansion-card like gps, Radio etc.

So help us to make a Community around it.

Featuers that comes with V3

Have RTC & buzzer.
Supports a lots of Add-os, see all of them from here.
5 row, 56 key customizable keyboard

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.

Sneak peek to mutantC v4 power circuit
rahmanshaber • 02/12/2021 at 12:02 • 0 comments

I am testing the new power circuit for v4, this black PCB are from PCBway and that helped me to quickly test out the new changes. The production was fast and i got the PCB within 3 days.

I had to make the v4 because of 2 reasons, the power supply is not enough and a lot of tiny mistake i made on the scolding pads. now those pads are bigger and easy to solder.

But V4 and v3 are not compatibles in the size so there is no drop in replacements.
Some updates on power and dock connector
rahmanshaber • 01/24/2021 at 09:21 • 0 comments

I am thinking to use the module called MH-CD42 to replace the 2 module i am using for power.
i am thinking to use a USB C connector to replace the docking connector. THe only problem i am seeing is soldering and able to send tx/rx and i2c pins, as usb c have 4 pairs of pins, 1 pair for power, 1 for data, 1 pair cc and 1 pair for sbu. as cc used for Power delivery things so that pair can't be used.
What you guys think? any input is welcome.

Message to hackaday and A replacement in a part
rahmanshaber • 10/25/2020 at 02:48 • 0 comments

Hi, My project is a small one and easy one. Even though hackaday covered v1 and v3 and got attention but i don't know why it did not covered v3 yet. V3 is the finest among other two and more easy to build. I hope hackaday will cover it in their blogs and let people know about it.
PART UPDATE
An update on headers, use this headers, 2.54mm pitch x 5mm height female headers instead of old size one.
i can't find that header in the amazon or aliexpress. fond this but they are smd part. if you find the part in through hole then let me know here.( I got mine from local shop)

Order your prebuilt mutantC v3 (not officially)

So open source licensing is paying off.
As mutantC is a open source hardware and I am not capable to supply you guys one by tindy or other way, so kwlodraczyk took the job to supply you guys one by his own.

I saw this post in Reddit and that made me so glad so I wanted to shear.
