Honeywell HMR3200/HMR3300 Digital Compass User Manual
This manual describes the Honeywell HMR3200 and HMR3300 digital compass modules, which offer compact size (25 mm × 37 mm × 10 mm) and low weight (≈7 g). The devices measure three‑axis magnetic fields with a range of ±2 Gauss and provide tilt‑angle measurement up to ±60°.
The document details electrical requirements (6‑15 VDC supply), UART and SPI communication protocols, pin assignments, and example command formats for direction and magnetic‑field output. It also lists the available demo kits and software support for easy integration into navigation and guidance systems. This manual is written in Chinese.
