# DJI Mic Mini Monitor: decoding the receiver's USB status stream

> DJI Mic Mini Monitor reads transmitter battery and charging state from the receiver's USB status stream on Windows. Its Python reader uses WinUSB, while protocol notes describe MI_06 bulk endpoints, frame boundaries, CRC checks and status offsets; the author reports checking those details against a local receiver.

## Requirements & limits

- **Prerequisites:** Windows 10 or 11 x64, a USB-connected DJI Mic Mini receiver, and a WinUSB binding for its MI_06 interface.
- **Prerequisites:** Source use requires Python 3.9+ with tkinter; tray functions also use pystray and Pillow.
- **Limits:** Read-only status monitoring; receiver battery level is unavailable, and two-transmitter use has not been tested on hardware.
- **License:** MIT license.
