: The schematic shows that the 5V boost converter (TPS61253) can be disabled by lifting its EN pin. This saves ~20mA battery drain.

Let's walk through the schematic’s major blocks as documented by reverse engineers.

Before diving into the schematic, let’s map the major components on the physical board. The JDM-055 measures roughly 60mm x 95mm and is a 4-layer board.

Technicians primarily use the schematic to trace common failure points in the following areas: 1. Power Management and Charging

Often utilizes the InvenSense MPU-9250 , which provides a lower noise floor and better temperature stability for motion-sensing compared to older models.
