{"title":"HMC6343 Qwiic Digital Compass","handle":"sparkfun-digital-compass-hmc6343-qwiic","url":"/products/sparkfun-digital-compass-hmc6343-qwiic","description":"This compact digital compass module is built around the HMC6343, a fully integrated electronic compass designed to deliver reliable heading data without making your main microcontroller do all the processing.Unlike basic magnetometers that need to be kept flat, the HMC6343 combines 3-axis magneto-resistive sensors with 3-axis MEMS accelerometers. Its onboard microprocessor fuses the data to provide tilt-compensated heading information, so readings stay useful when the board is angled, moving, or handheld.Integration is straightforward with the Qwiic Connect System: use the two Qwiic connectors to add it to an I2C chain without soldering. Standard 0.1\" pins are also broken out for breadboard-style connections.Documentation includes a schematic, KiCad files, hookup guide, HMC6343 datasheet, Arduino library with example code, and a GitHub repository.Features:Heading Computation: It outputs a final heading direction accurate to within a couple of degrees.Hard-Iron Calibration: It automatically compensates for magnetic distortion, maintaining accuracy in environments with magnetic interference.Rapid Updates: The board computes and outputs fresh data every 200ms (5Hz), ideal for real-time control loops.Compass with Heading/Tilt Outputs3-axis MR Sensors, Accelerometers, and a Microprocessor in a Single PackageEEPROM Memory2x Qwiic ConnectorsRed Power LEDSpecifications:Operating Voltage: 3.3VRun Mode Current: 4.5mAA strong choice for robotics, navigation, handheld instruments, and other projects that need heading data over I2C with minimal wiring.","vendor":"SparkFun","product_type":"Digital Compass","in_stock":true,"options":[],"variants":[{"id":15576,"title":"Default Title","sku":"SF-SEN-30183","mpn":"SEN-30183","price":687.36,"on_sale":false,"in_stock":true,"available_quantity":59}]}
