OI!STER

Jump to: navigation, search

The OI!STER is an STM32L5 Target Board with a QFP48 clamshell socket aimed at debugging and glitching salvaged MCUs. The board can be powered via USB-C, a 2032 coin cell battery on the back of the board or an external power suppy. All pins are broken out in the 24-pin headers on either side at the top of the board. The OI!STER contains five debug headers, to support a wide range of debugging hardware such as a Hydrabus or a Black Magic Probe. It comes with six SMA connectors arranged in I/O pairs. One pair is dedicated to glitching the external LSE clock, another for glitching the external HSE clock and one pair for power analysis and fault injection with a Chipwhisperer. Each SMA connector can by bypassed by removing a small jumper. The OI!STER also has additional solder jumpers for the external clocks and each of the power traces to the MCU to allow for quick experimentation.

A full pinout and additional documentation is currently under development.
