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.
This daughterboard uses an interesting set of 10 castellated pins - given the number of pins, similarities in board layout to the Apple Watch USB-C charging cable (see this other ChargerLab teardown video), and nearby USB silkscreen, I think this might be an internal USB-C header.
Based on a visual inspection/probe test, many of the 10 pins are either not connected or shorted to ground. This further leads me to think either USB-C, or USB 3.0.
Goal here: I have one of these chargers, but no Apple Watch. I'd like to replace the Apple Watch puck/charger with one for my watch, which is a physically identical size.
I've already gotten the puck to work in the housing, and wired it all the way back to the main board, but I need to figure out the pinout/compatibility for the USB-C charger I'd be replacing it with.
Looking forward to any information folks might gave.
