Direct-plug RP2040 six-axis 3D printer motherboard

This is a stable, high-performance 6-axis 3D printer motherboard with direct-plug capability, based on the JLCPCB RP2040 direct-plug king version: https://oshwhub.com/yoshino/rp2040-spi-tong-xun-da-yin-ji-zhi-cha-jian-zhu-ban. It's soldered onto my own 0.1 and TT printers and is compatible with printers like the BigFish TT and CC, Gugu Chicken, Voron 0.1, and Trident, but only works with Klipper and not Marlin. My own Voron 0.1 and TT printers have been used for approximately 300 hours. The motherboard operates at 12-24V, with a maximum current support of 20A for the heated bed interface and a maximum output of 10A for the extruder heating rod interface. Configuration: 1. Full-axis UART support: Compatible with TMC2209/2208/2225/2226 and other UART drivers. 2: Three controllable fans; 3: Two thermistors; 4: Three limit switches and one probe limit switch with optical isolation, the probes support NPN and PNP; 5: The heated bed, heating rod, and fans all have optical isolation (the MOSFET for the heated bed thermistor can be matched with different power ratings).
