M5PORT EXPLAIN
You can identify the port name and function by its color, red is
PortA(21/22) mainly used for I2C, black is PortB(26/36) which can be used for DA/AD, Singel-bus
communication, Blue is PortC(16/17) can be used for Uart. Correspondingly, most of the M5 Units have
the Port with matched color for specify which port it should go in on the M5Core. Those port
identification is a convenience for UIFlow (Blockly) Users. For advanced using ,you can do you own
customization, since most of the PIN on ESP32 are remapping-able. Unfortunatly, PortA(red) can not be
used as analog read in. It refers to GPIO 21 & 22 from ESP32, which doesn't have AD channel alternatives:
ADC1(8 channels atteched to GPIOs 32-39)
ADC2(10 channels atteched to GPIOs 0

To use AD read function : 1, Use Dupont cable refers to the pins on the side which can be used as an AD
channel. 2, Get a M5GO bottom, which comes with a PortB. 3, Get a PbHUB and connect it with PortA,
then you can have 6 PortBs. For more information about Pin assignment and Pin Remapping, Please refer
