GPIO mapping of APP3.0 shuttle board pins¶
The APP3.0 shuttle board has a total of 16 pins, 7 on the left and 9 on the right.(with shuttle board pins facing downwards).
Note:
- In coinesAPI the pins are addressed as on the APP3.0 shuttle board. For example, the GPIO #5 is addressed as
COINES_MINI_SHUTTLE_PIN_2_6
. - Supported VDD voltages on APP3.0 board are 0, 1.8V and 2.8V.
-
Supported VDDIO voltage on APP3.0 board is 1.8V.
