    • "Bottom" IO expander pinout

      Hello everybody !

      I've ordered M5Stack Basic kit and I'm preparing my project.

      I'm not able to find any schematic / picture that describes the link between MBus to IO of the Bottom module

      Following Schematic:
      MBus have 30 pins with 20 GPIO
      0_1524591940602_MBus.png

      Following Bottom module picture:
      Bottom module come with 46 pins with 30 IO...
      0_1524592014196_Bottom pinout.jpg

      I can figure out connection for 5V, 3V3, GND, RST, BAT but for the other ???

      2 pins are named "DA". What does it mean ?
      "R0"/"T0": RX/TX from UART 1 ?
      "R2"/"T2": RX/TX from UART 2 ?
      "2" means GPIO2 ? So what "G2" means ?

      Anyone can help ? Do you have a document regarding that ?

      Many thanks for your help,
      Max
