Glad you got it working finally.
Wait so weāre using tx/rx not sda/scl?
interesting read here on the different types, I like the sound of silicone due to itās ability to handle temps(PU is a heat blocker?) itās ability to keep water out and the lack of any mechanical stress on the pcb
although must admit no experience with any of these
I canāt say Iāve ever observed any noticable heat increases and I donāt coat heatsinked components
Yeah see the masking for fets, presumably keep off their pins too which also get hot hot
Yeah I just try to seal around the fets externally
Looks like a good idea until a pick, scratch and drv change is needed, hopefully these ESCs donāt suffer from that, Iām gonna try it thanks for the pics
Lol well the idea is to give it the best chance of not failing at the start so you wonāt have to dig into it later
Iāve used silicone conformal spray for other boards that I keep outside! But just a lacquer would probably work
To all the owners of the photon, what do you plan to do in terms of lights ?
Got the 144led/m strip and waterproof connectors, havenāt decided exactly what Iām gonna do yet Oh and 12v to 5v stepdown, already using a battery to 12v3a stepdown
So you donāt really care of the 1A max of the reciever ? You just use it for data ? And plug the 5v of the led strip directly to the buck converter plugged into the battery right ?
Yeah donāt use the 5v from the vesc, only from converter
Alright I was plannin to do that as well. Is thereās any buck converter recommended ? I have a 12S battery My plan is to have front and rear lights + led strip in the middle. All powered thru buck converter and all soldered to reciever for data and turn on/off from remote. Making sure I understand everything

So my photon fell off a desk while charging and this happened
I notice the rear support pins are not soldered
@Wajdi you need to update the original post to reflect whatās in the remote, the PCBs you have posted at the top, have all the USB support pads, this PCB does not
If it was left with all the pads it wouldnāt break with one dropThe current USB port is held on by 2 support pins in front and just the USB pins at the back, thatās not acceptable
@scepterr Oups, sorry this happened to you seems like it took a hit at itās weakest spot.
That first micro usb on the prototype pcb was unfortunately out of production, the best alternative I could find was this one. If anyone can find a good micro usb with better support pins please let me know.
The one on diebiems is very strong. And you can find the footprint ready to go on github
Iāll be able to fix it and epoxy it down myself, but this will be a very common issue if not mitigated
