preenfm2 and preenfm3 / Re: PreenFM2 for sale built, working and cheap but with one issue.(SOLD)
« on: December 21, 2017, 10:26:51 PM »just as a follow up:
the voltage regulator (7805) was bogus, it only outputted 2.05 v and got very hot... replaced that and the preenfm is alive with wall wart! since this was a revC board i also did the oled modifications and added a shield to reduce the high frequency noise...
so now i have two preen fm's , nice!
merry christmas to everybody else as well :-)
I haven't got a clue what it was or what you did as someone built it for me - did they build it wrong or was it a duff part (the voltage reg)? Anyway, I'm glad you're happy, merry Xmas!
