Wlx896b Schematic Exclusive Access

However, its popularity has surged among hobbyists because it is often sold as a "generic" module without documentation. This is where the becomes the holy grail.

The board uses a tiny 26MHz crystal (X1) and a 32.768kHz RTC crystal (X2). The note from the schematics: The WLX896B will not start if the 32.768kHz crystal is missing even if the main 26MHz is present. This is because the PMIC uses the low-speed clock for its power sequencing FSM. wlx896b schematic exclusive
