About the Samd21-pmod PCB

Samd21-pmod is an open source Microchip SAM PCB design by joshajohnson, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 40.6 × 40 mm, with 29 components from 16 distinct parts.

Its main chip is the ATSAMD21E17A-M, from the Microchip SAM family. Other key parts include the AP2112K-3.3 and W25Q32JVSSIQ. By type, the board carries 11 capacitors, 6 resistors, 5 connectors, 3 ICs, 2 diodes and 1 fuse.

It belongs with the dev boards & breakouts designs in this gallery.

Samd21-pmod: common questions

What microcontroller does the Samd21-pmod use?

The Samd21-pmod is built around the ATSAMD21E17A-M, from the Microchip SAM family.

How big is the Samd21-pmod PCB?

The Samd21-pmod measures 40.6 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Samd21-pmod?

29 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Samd21-pmod design files?

From the joshajohnson/samd21-pmod repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Samd21-pmod design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which joshajohnson chose for the repository.

Can I test firmware for the Samd21-pmod 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.
