The EVC2S is an updated version of the EVC2. The features and accessories are modified based on user feedback and the USB interface is updated to use Type-C cabling. It has moved to a full surface mount process resulting in a better looking product. The devices still offers I2C/SPI/UART communication, a VMOD header and OLED display support.
Part number: EVC2S
The EVC2 is the continuation of a personal project from 2013. It was originally designed for I2C communication over USB for digital voltage control of the most common graphics card voltage controllers. Compared to the first generation, the EVC2 has greatly improved functionality, speed and reliability. It now supports up to three separate I2C lines, one SPI interface (with adjustable supply/IO voltage), one UART port and an on-board DAC for analog voltage control.

P80DB1L LPC Debug Card
The P80DB1L card allows you to display motherboard debug information sent to Port 80 on the LPC bus, even if there’s no such display on your motherboard. It uses an Altera/Intel Max V CPLD which decodes the debug data and displays them on a 7-segment display. The prerequisite is that there’s a TPM or LPC debug header on the motherboard. Pinouts of the card, cables and standard motherboard headers can be found here.
