i have to admit sometimes i can be a plain idiot! I was planning on playing with the STM32F4-Discovery some more today and wired something up. I saw some magic smoke!<\/p>\n
I quickly unplugged the power to test and see where and what blew and how. I made the IDIOTIC mistake of crossing power rails. So i went in with my trusty multimeter found nothing wrong again. So i thought i ruined it might as well plug it back to see if i can see what got fried by frying it some more \ud83d\ude42<\/p>\n
NO LIGHTS! Not even a power light! You might have got worried here but think about it… NO POWER LIGHT means something wrong with power portion. So i went in deeper and found out i BLEW the D1 which is a BAT60JFILM (DIODE SCHOTTKY 10V 3A), since i knew its a diode just to protect the PC from outside power, i remove it and simply bridged it. Tested it and it works fine!<\/p>\n
Now this isnt a FULL FIX, i will order replacement diodes from Mouser @ $0.12 each. I decided to order 10. Just in case. When it arrives ill solder it in and test it.<\/p>\n
This goes to show you, experience doesn’t mean mistakes wont happen. And anyone can be a idiot. \ud83d\ude42<\/p>\n\n","protected":false},"excerpt":{"rendered":"
