You can find it on ebay or aliexpress. Search for 30522 or 40103 which are the bosch internal numbers..

Hi guys,
a first big step forwards has been done on this board. A small batch of them have been produced and arrived today.
Only one minor design error has been detected until now which was easy to correct. After installing the Bootloader the speeduino flasher is uploading the firmware without any issues. Tunerstudio is automatically detecting the board while add/open a project and goes online. So stay tuned while the now following function tests have to be done. This project is completely open source and any progress will be also posted in the GitHub on https://github.com/oelprinz-org/BlitzboxBL49sp
Best regards,
Chris

Hi tooly. Is this board ever be build and tested? If yes, what problems stop it?
Looks very attractive for 1..2 cylinder engines
I saw https://www.nanoefi.com/ in alpha for about few years.
Tech specs are OK, but nether implemented. blitzbox2561cj125 looks more mature product than this?
