TeensyBat mainboard v0.8 + mic.

This is the second mainboard version made for the Teensy 4.1 development board.

This board holds all small components like microphone amplifier, charger and battery protection as well as the complete audioboard. This means you do not need to buy the Teensy audioboard but do still need the Teensy4.1 (version without headers, and you can use the version without ethernet)

This board has a cut-out for placing annadditional GPS receiver, and a position for a temperature sensor. It can accept two different 2.8" ili9341 lcd display (red PCB with q1 transistor)

This offer is just the mainboard with a rectangular microphone. 

Up until december 2022 I sold the V.07 pcb, this is the V0.8 pcb. Some errors were corrected but the size is the same and building instructions for V0.7 can be used.
