3.2 GPIO AND INTERRUPT PINS

The GL6509 has 14 GPIO pins.

3.3 ANTENNA CONNECTIONS

There are two versions of antenna connectivity: one via the U.FL connector and the other via the SMT pin
(RF Pin 37).

3.4 POWER PIN

It is recommended that all the power related pins are connected.

3.5 BOOT PIN

This general purpose input pin is used to boot the GL6509 module. This is reserved for debug purpose. Not
Connected

3.6 RESET PIN

Thi

s input pin is for reset of the module’s MCU.

Low active.
