Which microcontrollers do boards using the A7 use?
Most are built on ESP8266 (2).
How big is a typical board using the A7?
The median is 44 × 118 mm, and 0% are two-layer designs.
What is the most popular open source board using the A7?
By GitHub stars, 3210retro by DasBasti, with 9 stars.
Can I simulate one of these boards using the A7 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.
