We need National Rusefi Stockpile

Just ordered x25 of STM32F427ZIT6 since newark still had some stock

what are the next chips to go into NRS?

injector driver? what PN from mouser digiket? #67 what else is weird and will get harder to get?

UPDATE: current state https://docs.google.com/spreadsheets/d/1b7IPYyfKyIHk4CH44ngV3pRVWT6DP8RQN10WxqnUWNQ

I am super confused - JLC has availability at one price while lcsc lists none twice more expensive for C182078?

rusefillc commented 3 years ago

ordered LMR14030SDDAR and ISL9V3040S3S

@andreika-git @Qwerty-OFF I've just ordered some BM2LC105FJ-CE2

those are compact two channel injector drivers could be useful on our smaller boards like Harley or alpha etc
