Power glitcher
About the Power glitcher PCB
Power glitcher is an open source PCB design by cpey, published on GitHub under the MIT license. It is a 2-layer board measuring 46.3 × 40.2 mm, with 66 components from 31 distinct parts.
Other key parts include the AD9708AR, Opamp_Dual, TL081H, ICL7660 and LM2735XMF. By type, the board carries 25 capacitors, 23 resistors, 7 connectors, 5 ICs, 3 diodes and 2 transistors.

Board for injecting voltage glitches
Power glitcher circuit for voltage fault injection. Similar to [1], it includes a DAC, a non-inverting amplification stage, and a push-pull follower output circuit.
The board can function as ON/OFF switch, bypassing the DAC, by connecting a GPIO output to the J5 connector and short-circuiting JP1. Refer to the schematic for more details.
