I’m looking for a table with all pins used by the Argon One v2.
https://www.waveshare.com/wiki/PI4-CASE-ARGON-ONE:
BMC pin Function
=================
2 SDA.1 (I2C data)
3 SCL.1 (I2C clock)
4 GPIO.7 Shutdown button
14 TXD transmit UART <== Function?
22 GPIO.3 IR LED pin
23 GPIO.4 IR receiver pin
I2C bus 1 device address 0x1a is used to control the fan.
Q1) Is the table above complete?
Q2) Is the TXD pin only used to generate a shutdown?
