Arduino Nano Python EEPROM programmer through serial data connection This project is based in 99% on Ben Eater's EEPROM programmer. So all credits go to him for this wonderful invention.

The Arduino Nano is connected to the EEPROM chip and two 74595 ICs using a few wires. The 74595 ICs are shift registers that can convert serial data into parallel data or vice versa4.

Assuming the Arduino Nano clone isn’t using an amazingly high-quality EEPROM we can safely assume that most of us have nothing to worry about and our Arduinos will be functional for decades to come.

It combines an Arduino Nano (in this case, a clone) with a single resistor, a single capacitor, and a six pin angled header (with a cleverly bent pin) to enable programming UPDI devices over a USB ...

The Nano ESP32 supports both Micropython and Arduino programming languages, providing a clear path for those already familiar with one platform to easily switch back and forth as needed.
