GPIO Pins free on Fipy and Pytrack2
May I know what pins are free on a FiPY/Pytrack2 combo.
It seems that pin P4 SD_CMD, P8 SD_DAT and P23 SD_CLK are taken for SD card; pin P21 SCL and pin P22 SDA are for GPS and Accelerometer.
External IO header has routed with 6 GPIO pins, but, only 3 of them - EXT_IO1, EXT_IO2 & EXT_IO3 are available as free ports, others are actually mean for RGB_LED(EXT_IO0), SD_CMD(EXT_IO4) and SD_DAT(EXT_IO5).
Are there any more "free ports" for us with FiPy/Pytrack2 combo? for example, direct wire solder to the socket header on the pytrack2 board ? pin16? pin3?
The pin orientation at Pytrack2 "External IO header" https://docs.pycom.io/datasheets/expansionboards/pytrack2/ is incorrect. is there any way to highlight this to the relevant party?
