Wild Spy Open Source Timer: common questions

What microcontroller does the Wild Spy Open Source Timer use?

The Wild Spy Open Source Timer is built around the 1611-ATSAMD21E18A-MUT, from the Microchip SAM family.

How big is the Wild Spy Open Source Timer PCB?

The Wild Spy Open Source Timer measures 30 × 32.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Wild Spy Open Source Timer?

43 components, from 24 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 Wild Spy Open Source Timer design files?

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

Can I use the Wild Spy Open Source Timer design in my own project?

Yes, under the terms of its Apache-2.0 license, which Wild-Spy chose for the repository.

Can I test firmware for the Wild Spy Open Source Timer 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.
