Hi Erle Robotics team,
Does the pxfmini uses all the GPIO on the Raspberry pi?Can I still use some 4 GPIO for 2 modules I need to use on SCUBA 3 motors simple ROV?The module I would like to use are the ultrasonic HC-SR04 connect to GPIO21 (pin18) and GPIO23(pin16)?And another module DS18B20 which I am planning to connect to GPIO4(pin7)?Can you advice what are free general IO on raspberry pi I can use.This module will run on Pi to collect data like temp and the sea floor (pool floor depth)?
You're right the PXFmini does not use all the GPIOs. If you check the schematics, you will have what you're looking for:
All the ones named as RPI_GPIOx are available.
Hope it is you're looking for.
Thank you very much for the reply and noted.
