Given this schematic of the Argon, is the proper way to read the pin P0.05/AIN3 like this? int32_t voltage = analogRead(BATT); BATT is defined as pin 33 but I’m not sure what this relates to in the actual hardware. [Voltage Divider Circuit - Argon] thanks

The fifth column in this table is the source of truth for that. It’s the analog input channel a GPIO is connected to. There’s one of these tables in the Device OS source for every platform: particle-iot/device-os/blob/develop/hal/src/argon/pinmap_hal.c#L56 /* RGBB …
