CatWAN Tracker: common questions
What microcontroller does the CatWAN Tracker use?
The CatWAN Tracker is built around the ATSAMD21E, from the Microchip SAM family.
How big is the CatWAN Tracker PCB?
The CatWAN Tracker measures 71 × 42.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the CatWAN Tracker?
30 components, from 23 distinct parts. The full bill of materials is listed on this page.
Where can I download the CatWAN Tracker design files?
From the ElectronicCats/CatWAN_Trackers repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the CatWAN Tracker design in my own project?
The repository has no license, so all rights stay with ElectronicCats. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the CatWAN Tracker 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.
