ARMACHAT - Doomsday wireless QWERTY communicator

First experimental boot on ATSAMD51 M4 core 120 MHz, 512 KB flash, 192 KB RAM + 8MB SPI FLASH . Theoretically can run #circuitpython This board is originally designed as game console for https://arcade.makecode.com/

• I am only removed RTC support :) 
• Expecting troubles with sharing SPI between LORA and display

FUSION:

Take advantages from currently both version:

• POCKET: Samd21E18 (easy to solder), Keyboard layout 6x5 matrix
• DESKTOP: 18650 battery, bigger buttons easier to solder and better for ussage
• 76mm x 71mm is best compromise for comfortable keyboard, display and battery
• PCB front panel .... manufacturing on PCB factory make super cool look and no laser or other tools are required

It is made from special 2 layer laserable plastic
