Project SPECTRE (Speeduino PrintEd Circuit board TjeeRdiE). This is a PCB with the hardware to run speeduino on a STM32F407VE6T board from ebay. (Or a STM32 BLACK_F407VE as it is sometimes called). Schematics and more information on the cpu board can be found here: (https://github.com/mcauser/BLACK_F407VE) The case with connectors can be found here: https://nl.aliexpress.com/item/32839361268.html?spm=a2g0z.12010615.8148356.7.1da330edPBhz16
Latest version is 0.5.2
A stand alone Peak and Hold injector driver board is now seperate. See: https://github.com/Tjeerdie/Peak-And-hold-Driver
Take a look at the very informative manual for speeduino: https://speeduino.com/Speeduino_manual.pdf
How to load the firmware to the STM32 see: https://speeduino.com/forum/viewtopic.php?f=13&t=1914&p=26572#p26572
