Making an Arduino shield can be simpler than you think. This time I designed one to program Attiny and Atmega ...

Abstract: In order to solve the problem of low accuracy and efficiency in printed circuit board(PCB) defect detection using reference methods, a Transformer-YOLO network detection model is proposed.

& USB-connection with the SPI-Protocol, so you can read ROM and read / write to RAM. The new configured software and custom PCB is compatible with +5V (mostly USB) Arduino Nano or similar.
