SparkFun MicroMod SAMD51 Processor

With a 32-bit ARM Cortex-M4F MCU, the SparkFun MicroMod SAMD51 Processor Board is one powerful microcontroller packaged on a small board! The provides you with an economical and easy to use development platform if you're needing more power with minimal working space. With the M.2 MicroMod connector, connecting your SAMD51 Processor is a breeze. Simply match up the key on your processor's beveled edge connector to the key on the M.2 connector and secure it with a screw (included with all Carrier Boards). The SAMD51 is one of the most powerful and economical microcontrollers available so to be able to add it to your MicroMod Carrier Board is a huge advantage for your project!

The ATSAMD51J20 utilizes a 32-bit ARM Cortex-M4 processor with Floating Point Unit (FPU), running up to 120MHz, up to 1MB of flash memory, up to 256KB of SRAM with ECC, up to 6 SERCOM interfaces, and other features. This MicroMod SAMD51 even comes flashed with the same convenient UF2 bootloader like the SAMD51 Thing Plus and the RedBoard Turbo.


MicroMod is a modular interface ecosystem that connects a microcontroller “processor board” to various “carrier board” peripherals. Utilizing the M.2 standard, the MicroMod standard is designed to easily swap out processors on the fly. Pair a specialized carrier board for the project you need with your choice of compatible processor!

How to setup extra SPI, UART, and I2C serial ports on a SAMD-based boards.

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.
See all skill levels


Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

  • Does the ATSAMD51J20 have CAN-bus ? According to the data sheet it is the SAME51 version that has CAN-bus.

    • You are entirely correct, I misread the datasheet at some point. We have corrected and updated the hookup guide and schematic. Now they correctly reflect that they are general purpose pins being routed to the CAN pins on the micromod connector. Thanks again!
