Use GPIOs on rapidM2M Base Starter board

Hi,

I’m thinking about how to connect external circuits to the GPIOs of the rapidM2M base starter board. From the schematics (https://support.microtronics.com/block_diagram/rapidM2M_Base_Starter_Board_Schematic_300921.pdf) I figured out that GPIOs 0 to 4 are internally wired to the internal LEDs.

My question is how to use the GPIOs without the internal LEDs.

Answer: I learned that there are 0 Ohm resistors in the circuit which are intended to be soldered out if the internal circuit should not be used.

The resistors can be found on the backside of the board with a label.

Hope this is helpful!
