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 ...

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 ...

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 ...

[Kirill] wrote in to share his Arduino-based PIC programmer. It is capable of writing to the 18F family of chips, including 18F2XXX and 18F4XXX. We think that’s pretty exciting because this line of ...

Tired of waiting for that Arduino sketch to upload? Find yourself limited by code space? Optiboot eases both of these problems. The package is an alternative bootloader that runs at a higher baud rate ...

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.
