You can tweek the name of the board (see how to boards.txt, the board.txt is my example). Optional : I made a custom PCB, so you could send the gerber files to your pcb provider (i used jlcpcb.com) and make one. Then you'll need to solder every pins to the PCB (check the photos) and the double-end dupont line to the buttons/switches You can download the gerber file here : https://drive.google.com/file/d/19pEmVKapCboTJWVD-D5RFSGa5o8hH_UQ/view?usp=sharing You'll need: 40 Pin 1x40 Single Row Male And Female 2.54 Breakable Pin - https://www.aliexpress.com/item/32993182990.html?spm=a2g0o.productlist.0.0.1e525e1e3FzFCP&algo_pvid=dfd6228a-4eb3-4700-87db-5f6feb7b8b92&algo_exp_id=dfd6228a-4eb3-4700-87db-5f6feb7b8b92-0&pdp_ext_f=%7B%22sku_id%22%3A%2266952136433%22%7D 2.54mm Single Row Female for the arduino pro connection to the PCB - https://www.aliexpress.com/item/4000783921467.html?spm=a2g0s.9042311.0.0.27426c37z5evzG 2P and 5P double-end Dupont Line female-Female (https://www.aliexpress.com/item/32496338704.html?spm=a2g0s.9042311.0.0.27426c37R7cspc)
