Neotron 340ST

The Neotron 340ST is based on the ST 32F746G-DISCOVERY. This is an off-the-shelf evaluation-kit aimed at the hobbyist market featuring an STM32F7 SoC, a colour LCD display, audio output jack and expansion headers. It is not open-source hardware, but it is easily available from ST and it comes with schematics.
