GPIO Mapping for Telit Module


I’m using the Telit ME910C1-WW HAT with the Cat-M connection. The Telit module support using AT commands to control the GPIO port, but the ports do not map with the sigfab board GPIO numbers (from here: Technical Details)

E.g., when I tried to set the GPIO 3 to HIGH with AT#GPIO=3,1,1, the GPIO3 on the figure above does not successfully set to HIGH. I’m wondering if anyone knows the mapping between the modem GPIO port and the sigfab port? Or it is not supported on the sigfab board. Thanks!


All the GPIOs of the Telit modules are not mapped as mentioned in this technical details of the HAT. Only the minimum required pins such as power, sim and data pins are mapped.
