ES121 Dropped - Help a brotha out
« on: December 18, 2024, 06:12:30 am »
whats going on guys, i dropped my little screwdriver (miniware es121) and the screen broke, no big deal, ordered a replacement, but the drive of the screwdriver became sporadic and would go on and off in bursts while using it. Dove into it a little bit more and noticed a little crack on an smd component (in pics), so i used my exacto knife and pulled the piece to see if it indeed was a crack, and it was. it took off a little chunk to reveal some copper windings inside (at least thats what it looks to be)

I know the es121 is "open source" but i think that is just the firmware rather than hardware etc. so i could not find a component schematic

i do believe this is an SMD inductor but i thought to employ the you guys to help me investigate :).

here are my questions:

1: is this component in fact, an inductor?
2: do i just measure to find the dimensions, and then how do i correlate that to a size of component, in name, for ordering purposes
3: how do i find characteristics needed for this component (measuring mH or something along those lines)

I do appreciate the help, im very new to schematics and component level repair, and i appreciate any help.

Also, does a cracked component like an inductor mean its typically failed? and exhibiting the symptoms i described be possible from a faulty inductor? just want to see if im on the right track and not missing something, this component does happen to be right next to the 3 axis accelerometer - MX6208

This little crack might change inductor parameter a bit, but it still should be operable.

yeah thats what i thought, wonder if the accelerometer took a dump after the drop, i ended up finding the same physical sized inductor in a vape, im going to test it today, if it still functions the same way, ill change out the accelerometer

replaced the screen, its working however still exibiting the stuttering/stopping behavior,  thinking it may be the acceleromter but also maybe that chip next to the inductor, its a 6 pin surface mount, labeled THAG9 or THA69, cant find any info on it, any ideas? ill be ordering the accelerometer just thought might as well order that while im at it.
