The first hardware prototype made before, after iterations, is actually no longer usable. Especially in the case of unable to flash the firmware, it took several hours to toss.
Rationally speaking, it can be dismantled and the available parts can be used. But after all, it was the first prototype that I soldered myself, so I still spent some money and sent it to a master seller and asked him to repair it for me.
After repairing it, I don’t plan to move it anymore, just keep it like this, as a feeling.
