Which microcontrollers do boards using the DG403 use?
Most are built on AVR/Arduino (1) and STM32 (1).
How big is a typical board using the DG403?
The median is 31 × 91.7 mm, and 60% are two-layer designs.
What is the most popular open source board using the DG403?
By GitHub stars, Mixer by rabidaudio, with 31 stars.
Can I simulate one of these boards using the DG403 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.
