Pinout for the SAMD machine modules¶
The assignment of device functions to pins is very flexible. The same function may be used at different pins. The representation of the assignment choices are given by a table, which is a subset of the MCU’s Pin MUX table and is specific to each board, as the available pin set varies. The structure of the table is the same for each board, but the set of rows is different.

Description of the columns:
Pin - The number that is expected at
machine.Pin(n), if the pin is given as a number.GPIO - The GPIO name, which can be used as argument to
machine.Pin("name").Pin Name - The boards name, which can be used as argument to
machine.Pin("name").IRQ - The IRQ number assigned to that GPIO, used internally by
Pin.irq(). When usingPin.irq(), different pins must use different IRQsADC - The ADC channel assigned to the pin. When using ADC, different pins must not use the same ADC channel.
Serial - Two columns with optional Serial signal assignments. Both may be used. The cell content is device #/pad #. The pad # is the respective internal signal of that serial device. Details below.
TCC/TC - Two columns with assignments of the TCC modules for PWM. The cell content is device #/output #. For PWM, devices 0, 1, and 2 are used. The TC device pair 3/4 is used for
ticks_us().
SAMD21 UART assignments¶
The UART devices and signals must be chosen according to the following rules:
The TX signal must be at a Pin with pad numbers 2 or 0, like Pin D1 with serial device 0 or 2.
The RX pin may be assigned to one of the other pads.
Examples for Adafruit ItsyBitsy M0 Express:
uart 0 at pins D0/D1 This is the default UART at the RX/TX labelled pins
uart 1 at pins D12/D10
uart 2 at pins D0/D1
uart 3 at pins D11/D13
uart 4 at pins D2/D5
uart 5 at pins SCL/SDA
or other combinations. For hardware flow control, tx must be at pad 0, rx at pad 1, rts at pad 2 and cts at pad 3. This applies for instance to UART 3 or UART 1 at the pins D13/D11/D10/D12 for rx/tx/rts/cts.
SAMD21 I2C assignments¶
The I2C devices and signals must be chosen according to the following rules:
The SDA signal must be at a Pin with pad numbers 0.
The SCL signal must be at a Pin with pad numbers 1.
Examples for Adafruit ItsyBitsy M0 Express:
I2C 0 at Pin A3/A4
I2C 1 at pins D11/D13
I2C 2 at the pins D4/D3
I2C 3 at the pins SDA/SCL This is the default I2C device at the SDA/SCl labelled pin
I2C 4 at the pins A1/A2
I2C 5 at the pins SDA/SCL,
or other combinations.
SAMD21 SPI assignments¶
The SPI devices and signals must be chosen according to the following rules:
The following pad number pairs are suitable for MOSI/SCK: 0/1, 2/3, 3/1, and 0/3.
The MISO signal must be at a Pin with a different pad number than MOSI or SCK.
Examples for Adafruit ItsyBitsy M0 Express:
SPI 0 at pins D0/D4/D1
SPI 1 at pins D11/D12/D13
SPI 2 at pins D0/D4/D1
SPI 3 at pins D11/D12/D13
SPI 4 at Pin MOSI/MISO/SCK This is the default SPI device at the MOSI/MISO/SCK labelled pins.
or other combinations.
SAMD21 PWM assignments¶
The TCC/TC device numbers 0, 1 and 2 can be used for PWM. Device 0 has four channels, device 1 and 2 have two channels. So in total 3 different PWM frequencies can be used, and 8 different duty cycle values.
The DAC output for the Adafruit ItsyBitsy M0 Express board is available at the pin A0.

For the definition of the table columns see the explanation at the table for Adafruit ItsyBitsy M4 Express Adafruit ItsyBitsy M4 Express pin assignment table.
Default pin assignments: - UART 2 at pins PB27 and PB26, labelled RX and TX - I2C 4 at pins PA12 and PA13, labelled SCL0 and SDA0 - I2C 3 at pins PA16 and PA17, labelled SCL1 and SDA1 - SPI 5 at pins PB00, PB02 and PB03, labelle MISO, MOSI and SCK
There seems to be no default pin assignment for this board.

For the definition of the table columns see the explanation at the table for Adafruit ItsyBitsy M4 Express Adafruit ItsyBitsy M4 Express pin assignment table.
The default devices at the board are:
UART 1 at pins PB23/PB22, labelled RXD/TXD
I2C 5 at pins PA22/PA23, labelled SDA/SCL
SPI 4 at pins PB12/PB11/PB13, labelled MOSI, MISO and SCK
DAC output on pins PA02 and PA05, labelled A0 and A4
Scripts for creating the pin assignment tables¶
The tables shown above were created with small a Python script running on the target board:
from samd import pininfo
from machine import Pin
import os
def print_entry(e, txt):
print(txt, end=": ")
if e == 255:
print(" - ", end="")
else:
print("%d/%d" % (e >> 4, e & 0x0f), end="")
def print_pininfo(pin, info):
print("%3d" % pin, end=" ")
print("P%c%02d" % ("ABCD"[pin // 32], pin % 32), end="")
print(" %12s" % info[0], end="")
print(" IRQ:%2s" % (info[1] if info[1] != 255 else "-"), end="")
print(" ADC0:%2s" % (info[2] if info[2] != 255 else "-"), end="")
if len(info) == 7:
print_entry(info[3], " Serial1")
print_entry(info[4], " Serial2")
print_entry(info[5], " PWM1" if (info[5] >> 4) < 3 else " TC")
print_entry(info[6], " PWM2")
else:
print(" ADC1:%2s" % (info[3] if info[3] != 255 else "-"), end="")
print_entry(info[4], " Serial1")
print_entry(info[5], " Serial2")
print_entry(info[6], " TC")
print_entry(info[7], " PWM1")
print_entry(info[8], " PWM2")
print()
def tblkey(i):
name = i[1][0]
if name != "-":
if len(name) < 3:
return " " + name
else:
