About the Pmod samd21-usbc PCB

Pmod samd21-usbc is an open source Microchip SAM PCB design by TomKeddie, published on GitHub under the MIT license. It is a 2-layer board measuring 18.2 × 29 mm, with 20 components from 14 distinct parts.

Its main chip is the ATSAMD21G-A, from the Microchip SAM family. By type, the board carries 7 capacitors, 4 resistors, 3 connectors, 1 IC, 1 transistor and 1 crystal.

From the project

All CPU power is derived from the PMOD power pins. The VBUS pin on the usb connector is connected only to a test point.

Pmod samd21-usbc: common questions

What microcontroller does the Pmod samd21-usbc use?

The Pmod samd21-usbc is built around the ATSAMD21G-A, from the Microchip SAM family.

How big is the Pmod samd21-usbc PCB?

The Pmod samd21-usbc measures 18.2 × 29 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pmod samd21-usbc?

20 components, from 14 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Pmod samd21-usbc design files?

From the TomKeddie/prj-pmod repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Pmod samd21-usbc design in my own project?

Yes, under the terms of its MIT license, which TomKeddie chose for the repository.

Can I test firmware for the Pmod samd21-usbc without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
