What parts are used alongside the CH343P?
The HX6538, SY80004DQD, W25Q128JWSIQ and WR0331-18FF4R appear in the most repositories here.
Which microcontrollers do boards using the CH343P use?
Most are built on RP2040/RP2350 (1) and STM32 (1).
How big is a typical board using the CH343P?
The median is 40 × 20 mm, and 0% are two-layer designs.
What is the most popular open source board using the CH343P?
By GitHub stars, Astra piNas by jlcjak, with 28 stars.
Can I simulate one of these boards using the CH343P 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.
