Honeywell Commercial Switch&Sensor products have high direction accuracy, good repeatability, small size, and lightweight. The product can be used in applications such as directional navigation, attitude reference, satellite antenna positioning, platform leveling, and GPS integrated systems.
This manual describes the HMR3200 and HMR3300 magnetic compass modules, including their compact dimensions (25 mm × 37 mm × 10 mm), lightweight design (≈7.3 g), and operating temperature range of –40 °C to +85 °C. Both models support a magnetic field range of ±2 Gauss and offer tilt‑angle measurement up to ±60°.
The document details the electrical characteristics, UART and SPI communication protocols, pin assignments, and example commands for direction and magnetic‑field output. It also lists the demo PCB kits and required Windows software for development. This manual is written in Chinese.
