Hello,
I was searching for IOT device and found this device EFB-REV1-IoT i would like to know if someone tried to use its GPIO pins.

 

Yes at the back of the EFB-REV1 it has a 34 pin header
out of which you can only use 20 pins
which you can configure either GPIO/ADC/DAC/UART/SPI/I2C

the remaining pins are power supply pins and ground pin you can supply upto 2.5A current

see the pin details table and the header on the back of the device attached
