Which microcontrollers do boards using the MAX809S use?
Most are built on ESP32 (2), ESP8266 (1) and RP2040/RP2350 (1).
How big is a typical board using the MAX809S?
The median is 120.7 × 101.2 mm, and 75% are two-layer designs.
What is the most popular open source board using the MAX809S?
By GitHub stars, Fosdem dual capture by FOSDEM, with 114 stars.
Can I simulate one of these boards using the MAX809S 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.
