Which microcontrollers do boards using the CH217K use?
Most are built on RP2040/RP2350 (4), RISC-V (3), WCH CH32/CH55x (1) and ESP32 (1).
How big is a typical board using the CH217K?
The median is 50 × 54 mm, and 55% are two-layer designs.
What is the most popular open source board using the CH217K?
By GitHub stars, Ch32x035-promicro usb device by 74th, with 10 stars.
Can I simulate one of these boards using the CH217K 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.
