STM32F746 Discovery Kit

I bought this maybe 5 years ago (2020?) and it has been sitting in a box ever since.

These now sell for $57 at Digikey and are quite a bargain if you are the least bit interested.

This is a big board (3x5 inches) almost entirely covered with a big LCD. It has an ethernet connector on the side, three USB connectors (one for ST-Link) and an SD card slot. It also has the annoying Arduino connector for IO -- which will limit how many IO pins are available. And there is more!

You can find RM0385 (1713 pages) as a reference manual for the chip and UM1907 as a user manual for the board. And you can find a schematic.
Feedback? Questions? Drop me a line!
