Power
There are a variety of power and power-related nets broken out to female header pins and their corresponding
through hole pads. The image below highlights those female headers and pads. The board can be powered from
the VIN pin with a recommended voltage between 3.3V to 6.0V. It can also be powered with 5V from the USB C
connector. The voltage is regulated down to 3.3V with the AP7361C voltage regulator to power your devices with
up to 1A of current. If your voltage is clean, and regulated, you can also connect it directly to the 3.3V line.
Backup Battery
The board has a built-in backup battery for Processor Boards with an RTC. Depending on the processor, it may
not be connected
USB Ports
You have the option of connecting the board to a computer using the USB connectors. The USB Type C connector
is used to power, program the processor board, or pass serial data to a serial port. If your processor board has the
ability, there is also an option for USB host through the female USB Type A connector. There is a Schottky diode
on the USB host's 5V pin but we do not recommend connecting two both the Type C and Type A ports.

All the [GPIO] Pins
Remember our "All the Pins!" nickname? Well, we meant it. On the MicroMod ATP, not only have we broken out all
the major pins with female headers, we've added a secondary rail of plated through-holes alongside them to give
you the choice of either plug and play or soldering directly to the board. The general hardware pinout v1.0 is
broken out on the edge of the board. Your mileage may vary depending on the processor board that you are using.
Qwiic and I C
There are two locations on the board for your favorite Qwiic-enabled device. IN addition to the Qwiic conenctors,
we also have pins that are broken out on the should you need to use jumeper wires or solder wire direction to both
boards. There are mounting holes for each standard 1.0"x1.0" Qwiic-enabled device.
Reset and Boot Buttons
The reset button will reset the processor. The boot button will put the processor into a special boot mode.
Depending on the processor board, this boot pin may not be connected.

SWD Programming Pins
For advanced users, we broke out the SWD programming pins. Note that this is not populated so you will need a
compatible header and compatible JTAG programmer to connect.
Jumper Pads
There are a few jumpers populated on the board:
Bypass (BYP) - By default, the BYP is left open. Adding a solder jumper bypasses the 2A resettable fuse
on the back of the board should you decide to pull more than 2A from your USB source. Proceed with
caution should you decide to bypass the jumper.
Enable (EN) - By default, the EN pin is closed. This jumper is connected to a processor board's GPIO pin.
The processor board cna control the ATP's voltage regulator. Depending on the processor, this may not be
connected.
Current Measurement (MEAS) - By default, the MEAs is closed. Cutting the jumper and soldering to the
PTH pads will allow you to insert a current meter and precisely monitor the how much current your
application is consuming.
3V3 LED - By default, the 3V3 LED is closed. Cutting this jumper will disable the LED there is 3.3V.
VIN LED - By default, the VIN LED is closed. Cutting this jumper will disable the LED whenever there is an
input voltage.

General MicroMod Pinout
Wondering what the pins are that are broken out on the ATP MicroMod ATP Carrier Board? Check out the table
from the Getting Started with MicroMod for more information. Remember to check out the pins against your
Processor Board to determine what pins are available.

At a minimum, your setup should look like the image below. In this case, we had the MicroMod SAMD51
Processor Board secured in the M.2 connector. To program and power the microcontroller, we inserted the USB-C
cable.
Depending on your setup you may need hardware (jumper wire, cables, header pins, breadboard, etc.) to connect
to the board. In this case, we used jumper wire to connect to another board.
To Qwiic-ly connect C devices, simply insert a Qwiic cable between the MicroMod ATP's Qwiic port and your
Qwiic device.

To secure the boards together, you could add standoffs and screws to mount a Qwiic-enabled device that have the
standard 1.0"x1.0" sized board. Keep in mind that this will block a few of the header pins below so make sure to
plan accordingly.
Depending on the location of the mounting holes, you may need to make an adapter to hold the Qwiic-enabled
device securely. Below is an example with mounting holes on the same side instead of diagonal. A piece of
cardboard was cut out as shown in the image below. Depending on your personal preference, you could also laser
cut, CNC, or 3D printer to make a more sturdy panel for those that need a stronger material.
Example
Note: If this is your first time using Arduino IDE or board add-on, please review the following tutorials.
Installing the Arduino IDE
Installing Board Definitions in the Arduino IDE

There are quite a lot of peripherals broken out on the MicroMod ATP Carrier Board. Depending on the design of
the Processor Board, not all of the pins may be broken out. For simplicity, we will upload a blink sketch to get
started.
Blink
Note: Make sure that for whatever processor board you choose, you have the correct board definitions
installed. Go to our MicroMod Processor Boards landing page, find your processor board, and head on over
to that tutorial for help installing your board definition.
Now that you have a Processor Board secure in the Carrier Board, let's upload a simple blink sketch to the board.
Copy and paste the following code in the Arduino IDE. Head to Tools > Board to select the correct board
definition (in this case, SparkFun MicroMod SAMD51. Select the correct COM port that the board enumerated to.
Hit upload.
/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
This example code is in the public domain.
*/
// Pin 13 has an LED connected on most Arduino boards.
// give it a name
// uncomment the following lines if the macro is not defined for your architecture
//#define LED_BUILTIN 13 //Artemis, SAMD51
//#define LED_BUILTIN 5 //ESP32
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin using the built-in macro as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
After uploading, you should see the Processor Board's LED blink. If not, make sure that to define the pin and
check your connections.
What's next? Try building a circuit using the design files and associated tutorial for your Processor Board more
information. Keep in mind that while each Processor Board uses the same MicroMod interface pinout, each board
may have different specifications, software support, and peripherals available for the architecture.
