Basic

Order a PCB

Here I suggest using JLCPCB to make PCB (my template is also made by JLCPCB). Please note that the impedance needs to be 3313, and the PCB thickness needs to be 0.8mm to install the clamp-style TypeC connector

Supported USB output resolution table

Flash Firmware

USB Flash

Using ms-tools from @BertoldVdb

./cli --log-level=7 write-file --verify FLASH 0 YuzukiLOHCCPro.bin

SPI Programmer

Use an SPI NOR flasher to flash the firmware to the NOR Flash before soldering.

(Only one of U4 and U8 needs to be mounted, adding two SPI NOR pads are drawn to be compatible with different types of materials)

Unfortunately, I couldn't find a public version of the MS8003 code, but it's not expensive to buy a pre-programmed set
