I was trying some stuff on my manta board to reset it, and i tried doing it via the reset button, and since my fingers are pretty big for that tiny button i grapped a small screw driver and pressed the button. But when i moved back i bumped my finger and hit these pins:
Both sides of the fuse F13. If you see power on both sides and still no 5V and 3V3 then youâve blown the 5V power supply.
Checking continuity isnât enough - there could be a weak connection in the fuse that doesnât hold up under load. Itâs a faint hope but a blown fuse is better than a blown 5V power supply.
If you can afford a new one, along with the new Manta M8P V1.0, then itâs probably a good idea to order one with it.
i can but i wonât atm. i will order the Manta M8P V2.0 just like now, everything is fitted for that board (otherwise i may need to repint all the mounts).
and i assume that the V2.0 is better than the V1.0
I will wait for it to come in and continue form there.
Itâs not a âmoduleâ. Itâs a chip and some other components (which might also be damaged).
If you have the tools and skills to remove the TPS5450 and put in a new one then you can try, itâs about $6.00 USD at Digi-Key.
I should warn you that itâs not trivial to replace the part as it has a large power pad on the bottom that is soldered to the PCB - youâll have to have the appropriate hot air tools or thereâs a good change youâll further damage the board (if you just have a soldering iron then forget it).
