Which microcontrollers do boards using the DFR0299 use?
Most are built on ESP32 (4), AVR/Arduino (3), ESP8266 (1) and RP2040/RP2350 (1).
How big is a typical board using the DFR0299?
The median is 99.1 × 99.5 mm, and 100% are two-layer designs.
What is the most popular open source board using the DFR0299?
By GitHub stars, Sampler by ijnekenamay, with 142 stars.
Can I simulate one of these boards using the DFR0299 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.
