| YUKI PCB | 2 | KiCad project files can be found in yuki_pcb directory. I ordered them from JLCPCB. They are reversible so you will use the same pcb for both left and right. |
| STM32F401CCU6 | 2 | Can be found on aliexpress. I have ordered mine from a local vendor. |
| TRRS jacks | 2 | PJ-320A |
| TRRS cable | 1 | 3.5mm jack cable, with 3 stripes. |

You will need rust installed so:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
cargo-binutils for stripping unused data from the rust binary and other optimizations:
rustup component add llvm-tools
cargo install cargo-binutils
dfu-util for flashing:
sudo pacman -S dfu-util
add the rust target for the MCU:
rustup target add thumbv7em-none-eabihf
then to compile the firmware:
cargo objcopy --bin yuki --release -- -O binary yuki.bin
for the right board add --features right
to flash enter dfu by holding BOOT clicking RESET and releasing BOOT and enter (can be tricky):
dfu-util -d 0483:df11 -a 0 --dfuse-address 0x08000000:leave -D yuki.bin"
After that to enter dfu just hold button 05 and 33 click reset and release the buttons.
if you are on NixOS you could use the devShell:
enter the dev shell:
nix develop
and use the flash script that can be found in flash.nix
flash right
