About the SAMD21 Dev Board

SAMD21 Dev Board is an open source Microchip SAM PCB design by 4project-co-il, published on GitHub under the MIT license. It is a 2-layer board measuring 55.4 × 87.4 mm, with 60 components from 26 distinct parts.

Its main chip is the C78624, from the Microchip SAM family. Other key parts include the C295762 and C114502. By type, the board carries 21 capacitors, 17 connectors, 11 resistors, 4 diodes, 3 ICs and 1 transistor.

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

From the project

Plug-n-Play SAMD21 Development Board

The PlugAndPlay system is an arduino-based environment that allows easier connections between the parts and intended to create a more "product-like" projects with permanent connections, compared to a breadboard.

PlugAndPlay parts do not require any soldering to connect. Just plug the cable to the connectors and you are ready to go. In the worst case, you might need to tighten few screws on a terminal block.

SAMD21 Dev Board: common questions

What microcontroller does the SAMD21 Dev Board use?

The SAMD21 Dev Board is built around the C78624, from the Microchip SAM family.

How big is the SAMD21 Dev Board?

The SAMD21 Dev Board measures 55.4 × 87.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SAMD21 Dev Board?

60 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the SAMD21 Dev Board design files?

From the 4project-co-il/PlugAndPlay-SAMD21 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 Dev Board design in my own project?

Yes, under the terms of its MIT license, which 4project-co-il chose for the repository.

Can I test firmware for the SAMD21 Dev Board 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.
