Уважаемый!Какой контакт J5 отвечает за нее?
Not complete, may never be honestly. If you find any errors or have any known component values to contribute go for it, but I'm not in any kind of race to make this thing 100% complete, so it'll get updated when it gets updated as I'll have to verify any errors/values anyway before making changes.

At that point I could have gone component by component to get all of the values recorded, but I just wasn't in the mood and wiped the thing clean to get at the meat of it. Being a 4 layer PCB it's the best way to go about it, unless you have access to a flying probe machine that can do a million continuity checks in a minute, plus want to spend all day programming in all the spots it needs to check. The PCB has 774 vias, for anyone that was curious.IMPRESIONANTE tu aporte, tu voluntad, tu tiempo, lo que nos aportas...muchas gracias.Luis de San Juan-Argentina
Thanks.I haven't seen or heard of anything specifically causing that issue. The BT is built into the MCU chip now, so unless the filter network for it right before the antenna is all messed up there's not really much that can be done when just that part of it goes bad. Same for if the battery charging is all that dies, you have to replace that entire PMIC chip that does everything else on there because that one little section of it decided to stop working. It's a bit worse when it comes to the MCU because it has to come from another controller so it's been programmed correctly, so you have to harvest that MCU from another working controller, or at least one that is damaged in some other way and the MCU is still good on, there's no other place to get that replacement part from.
Hello friend, thanks a lot!! Do you have information about JDM-040, 030, etc.?How can I get them? fantastic job
