With a 32-bit ARM Cortex-M4F MCU, the SparkFun MicroMod SAMD51 Processor Board is one powerful microcontroller packaged on a small board! The board 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!

MicroMod SAMD51 Processor Documentation:
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.
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.

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.
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.

I ordered this module in 2021, when the first revision came out. I ran into issues with the external flash module, which turned out to be due to a flaw in the board routing for the SPI interface. Sparkfun acknowledged the issue and sent me a new module when the 1.3 revision came out.
Sadly, the new revision appears to be flawed as well. A check of the board showed that the fix made for the SPI was partial, with one pair of pads still swapped. So it's not really a fix at all.
I don't see how this module was fully tested in either revision, which is really disappointing. I've been a Sparkfun customer for years, and I've trusted them to build quality products. But this one let me down.
There's more detail on the issues with this board in a couple of forum threads.
Update: it turns out the v1.3 module I got has an ATSAME53J19A instead of the ATSAMD51J20A. This is probably due to the chip shortage, but it’s a lower spec chip in terms of RAM and ob-board flash. However, I was wrong about the SPI flash: the new routing does work.
Greetings. Thank you for reaching out and bringing this issue to our attention. if you would like to submit a return ticket we can look into this issue further and get you taken care of regarding the ATSAME53J19A / ATSAMD51J20A mislabeling problem brought up in your edit:
