Hi there,
I'm looking for anyone who might have information on Apple's embedded Apple Watch charging daughterboard, ID 820-02601. This is currently used by Anker in their Apple Watch charging products, but likely by other Apple partner brands as well.
You can see the board referenced in ChargerLab's teardown of the Anker Y1811 3-in-1 MagSafe cube - they discuss the "Apple Watch wireless charging circuit" about 2/3rds down the page. It's not pictured, but the board ID reads 820-02601-A, which sure sounds like Apple.

Hallo everyone, my A1398 do not charging the battery and the battery also do not bin recognized. I did all the reset work, SMC reset and all the other reset options but nothing helped. on the SMC at pin 2 (DCIN) there are 20,4V coming in. at pin 16 (BGATE) which goes to the Q7155 Gate there are only 11,43V. at the pin 1,2 and 3 on the Q7155 (Source) there are 12,23V. Cap C7126 is not shorted. As I understand, the gate voltege have to by higher then the source voltege for the gate to clous so the battery can be charging, am I right? can someone help me with this? I guess that manny models are working... -
Hi all,
I have a MBP A1398 EMC 2881 here, it chimes, boots and shows picture on external screen
there is an apple logo on the display, no backlit
I measured the PP3_G3H on the backlit fuse - it's 12.6V when not powered and it drops to 10.8V after startup.
Is this OK?
Also measured the LVDS connector pin 1, there is 0V, could that be the backlit driver chip?
Also checked all 4 "backlit" capacitors, all OK, not shorted.
Thank you very much,
