WARNING:

GPIO’s marked with (*) should not be pulled high externally (by the carrier

board) during module power on procedure. Pulling those pads high during

module power up might lead to unwanted/non-operational boot mode.

The additional GPIOs below can be used in case their initial functionality is not used:
