About the Playground PCB

Playground is an open source Microchip SAM PCB design by glingy, published on GitHub. It is a 2-layer board measuring 45.7 × 43.2 mm, with 59 components from 19 distinct parts.

Its main chip is the ATSAMD21E15L-A, from the Microchip SAM family. Other key parts include the MIC5365-3.3YC5, SK9822 and ATSAMD21E16B-U. By type, the board carries 24 resistors, 12 capacitors, 11 diodes, 4 ICs, 3 connectors and 3 switches.

This repository contains the development kit for building code for the Atmel SAM D21 playground board. This board was developed to help members of the Solar Car Club (Prisum) at Iowa State University to learn how to program very low level embedded code. This repository is a reduced version of the development environment used by the team.

Help! A peripheral isn't working! - Is it enabled in APB? - Did you wait after enabling it for the clock to enable? - Does it need AHB enabled? - Is it enabled? - Is its GCLK enabled?

Playground: common questions

What microcontroller does the Playground use?

The Playground is built around the ATSAMD21E15L-A, from the Microchip SAM family.

How big is the Playground PCB?

The Playground measures 45.7 × 43.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Playground?

59 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Playground design files?

From the glingy/playground repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Playground design in my own project?

The repository has no license, so all rights stay with glingy. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Playground 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.
