Pin Layout

CN21 Pin Header

The green-framed pins of CN21 are working with 3.3V I/O without level-shifting and connected to the terminal of TMPM3HQ.


CN5 Pin Header

The green-framed pins of CN5 are working with 3.3V I/O without level-shifting and connected to the terminal of TMPM3HQ.


CN12 Pin Header

The green-framed pins of CN12 are working with 3.3V I/O without level-shifting and connected to the terminal of TMPM3HQ.


CN9 Pin Header

The green-framed pins of CN9 are connected to the terminal of TMPM3HQ and working with 3.3V I/O without level-shifting, therefore PF2 to PF7 can work as Analog IN with maximum voltage of 3.3V.


Arduino Pin Header

When you use Arduino pin, you need to short that connected Arduino pin on CN21, CN12, CN5, and CN9. E.g. short: 1-2, 3-4, 5-6 etc: CN9 Arduino pin header of AdBun-M3HQ Supports 5V I/O only. PF2 to PF7 with level-shifting cannot work as Analog IN anymore.



Arduino Pin Header Usage Setting

When using the Arduino's pin header, it is necessary to short-circuit the red line as shown below.

On Board Peripheral Usage Setting

When using LED, Push SW, volume, USB and Dip SW on the AdBun-M3HQ board, it is necessary to short-circuit the red line as shown below. The purple line is shorted at shipment. If your AdBun-M3HQ is not shorted purple line, you need to short-circuit purple line.
