TSOM_A7 / D7 A7 Analog in, GPIO D7, PWM, SPI SS, WKP ADC3 38 P0.05
TSOM_A6 / D6 A6 Analog in, GPIO D6, PWM, SPI (SCK) ADC2 39 P0.04
TSOM_A5 / D5 A5 Analog in, GPIO D5, PWM, SPI MISO ADC5 40 P0.29
TSOM_A4 / D4 A4 Analog in, GPIO D4, PWM, SPI MOSI ADC7 41 P0.29
TSOM_A2_BUTTON / D2 External user button, A2 Analog in, GPIO D2, PWM ADC4 57 P0.28
TSOM_A3_BATT_TEMP /
D3 Battery temperature sensor, A3 Analog in, GPIO D3,
PWM
ADC6 58 P0.30
On the Monitor One, you should not use A2 and A3 as analog inputs as they are used by the
external user button and battery temperature thermistor.

TSOM_A0_SDA / D0 Wire SDA Wire (SDA) 55 P0.03
TSOM_A1_SCL / D1 Wire SCL Wire (SCL) 56 P0.02

On the Monitor One, pins A0 and A1 are used in I2C mode by the user RGB LED and temperature
sensor. Pins A0 and A1 cannot be used as GPIO.
On the Monitor One (and Tracker SoM),
Wire
and
Wire3
are two different I2C peripherals and
can be used at the same time.
On the Monitor One (and Tracker SoM),
Wire3 and Serial1 share the same pins and only one
can be used at a time.
I2C is 3.3V only and is not 5V tolerant.
There are 4.7K pull-up resistors on
TSOM_A0_SDA and TSOM_A1_SCL to 3.3V on the base board.

On the Monitor One (and Tracker SoM),
Wire3
and
Serial1
share the same pins and only one
can be used at a time.
Hardware flow control is not available on the Monitor One.
Serial pins are 3.3V only and are not 5V tolerant.
Additional interface chips are required for other serial standards such as RS232 and RS485.
