The Snifferlyzer is a simple cartridge that provides a buffered input to allow logic analyzer functionality. It's using the OnSemi 74LCX16245, that has 5V tolerant inputs and the configuration pins for the transceiver is also hooked up to the badge, allowing full control over the direction of the two 8bit banks.
This cartridge is based on the unofficial Superconference 2019 Badge Cartridge template and hence include the w25q128 SPI flash and a 100nF cap in addition to the 2x20 pin angled male pin header for the badge connection. The flash allows badge configurations and firmware specific to this cartridge to be loaded from the cartridge it self making it selfcontained.
This updated version fixes an error in the pin connections on the cartridge connector (the two columns was flipped for some signals).
If you want to use a PCB based on the original version with incorrect connections, it is possible to make a hardware hack on the 20x2 angeled header, where you move the pins around and bend some of them a bit, very precisely.
