Which microcontrollers do boards using the ATSAMD21E use?
Most are built on Microchip SAM (4).
How big is a typical board using the ATSAMD21E?
The median is 55.9 × 50.4 mm, and 50% are two-layer designs.
What is the most popular open source board using the ATSAMD21E?
By GitHub stars, Nigun by raziele, with 40 stars.
Can I simulate one of these boards using the ATSAMD21E before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
