backside jumper setup
please refer to the image below
- top-left capacitor for genesis arduino
- network resistor for genesis arduino
- pullup resistors in the middle for I2C
- power supply selector by 3-way SMD jumper
Note:
- Crystal no placed default, the MCU can use internal clock for most cases.
-
Default power selection by 3-way jumper on board, default on 5V.
- Will build next version TQFP-48 footprint IC, nearly same cost but more functions.
