What boards using the CH217K are built for
CH217K: common questions
Where can I find a CH217K reference design?
Each of the 4 boards on this page is a real design using the CH217K. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the CH217K use?
Most are built on RISC-V (2) and ESP32 (1).
How big is a typical board using the CH217K?
The median is 28.1 × 37.9 mm, and 100% are two-layer designs.
What is the most popular open source board using the CH217K?
By GitHub stars, WiFi KeyMouse by 74th, with 1 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.
