usb-spi2

1 month ago

Profile:Simple USB-SPI bridge. Couldn't find a suitable board, so decided to make one. The long connector in the middle, should fit those SPI LCD screens, 2.2 - 4.0" Goal was to use a USB to SPI chip that came with Linux drivers. Other vendors (e.g. Holtek) use proprietary libraries and support Windows only.
