This project creates a complete standalone ISP programmer for Arduino Nano devices using another Arduino Nano as the programmer. It's designed to program the Optiboot bootloader onto ATmega328P ...

Since you lacked the USB interface in your own Arduino board, it becomes necessary to use a homemade/ready-made USB to Serial Converter Module as an efficient and economical solution. Inexpensive and ...

In some platforms like arduino:zephyr, the bootloader could be uploaded with the same protocol as the uploader, so there is no reason to require the programmer.

There are many reasons to build your own Arduino circuit on a protoboard or a custom-designed printed circuit board. At the heart of the Arduino platform is an AVR microcontroller, in usual way you ...
