The EVC2 is soon ready for release and should be available in mid-June. It’s estimated to cost 35 USD without the OLED display which will be a 5 USD add-on.

Additional information
- SOIC8 test clip can be bought separately for Gigabyte boards, they don’t have any on-board header
- I2C1 supports I2C listening/sniffing to figure out what’s being sent on the bus it’s connected to, which is very useful for figuring out how to talk to undocumented ICs
- I2C3 supports SSD1306 128x64px I2C OLED displays as seen in Roman’s video for displaying various information (optional add-on)
- The SPI header is targeted for external BIOS flashing. Can be very useful for flashing mod-BIOS or recovery. Can also be used to update the EC firmware on some boards.
