Look, [lord feistel] is doing glitching attacks on an ATMega328P! All you need is an Arduino board with its few SMD capacitors removed or a bare 328P chip, a FET, and some sort of MCU to drive it.

[Rafael] just made a little library that allows you to interface these modules to the Atmega328p-based Arduino UNO in order to gain some memory space. His work was actually based on the great ...

and there are “no plans to discontinue the popular Uno R3” , according to Arduino, which estimates that R4 will deliver a 3x performance boost over the 8bit ATmega328P equipped R3. Scheduled to appear ...
