Was just wondering if there was an ARM64 build of this for Apple Silicon? For now the Intel version seems to work fine. Thanks! -
Resistance is to ground is very high at ~10 Mohms....Leave a comment:

Sorry, just realized a mistake in my original post - I meant to say 12V not 3.3V. It should read:
"This makes me believe that RD560 has failed and is not supplying CC721/UC710 with 12V. This is a common issue according to other threads I've read."
CC721/UC710 is only receiving 2.76V on my board at the moment.Leave a comment:

Thank you for explaining that. Here were the threads I was referencing that pointed me to RD560:
I do not believe UC710 is getting 12V on my board because PPBUS_AON_3V3S2_VIN_ISNS is only getting 2.76V (measured at CC721).
Not sure if I'm able to get a good reading - seeing 65K Ohms. It climbs (charging?) but slows to 65.
Thanks for your help....Leave a comment:

MacBook Pro M1 A2338 820-02020 - No WiFI/Bluetooth or internal display
Hello,
I have a MacBook Pro M1 A2338 820-02020. It boots to OS but WiFi/Bluetooth are non-functional (exclamation point through WiFi symbol in menu bar) and the display is not working.
Starting at the WiFi chip... PP3V3_S2_WLBT_ISNS is fluctuating at around 2.4V. No shorts detected around UL000.
PPBUS_AON is 12V steady, but PPBUS_AON_3V3_S2_VIN_ISNS (measured at CC721) is 2.76V.
LC710 is getting 2.4V at P3V3_SW, which explains PP3V3_S2 fluctuating around 2.4V.
No detected shorts around UC710.
This makes me believe that RD560 has failed and...Last edited by mcbadcbv; 07-28-2025, 07:11 PM.
