GYD-9E Datasheet — Overview and Key Specifications The GYD-9E is a compact, low-power, high-accuracy inertial measurement unit (IMU) combining a 3-axis gyroscope and a 3-axis accelerometer in a single package. It is designed for motion sensing, stabilization, navigation, and inertial-aiding applications in consumer electronics, robotics, UAVs, and wearable devices. Key Features
6-axis inertial sensing: 3-axis gyroscope + 3-axis accelerometer Small form factor, surface-mount package Low power consumption for battery-powered systems SPI and I2C compatible digital interfaces Programmable full-scale ranges and data rates Built-in temperature sensor and basic self-test On-board digital filtering and calibration offsets Typical applications: stabilization, dead-reckoning, gesture recognition, IMU fusion with magnetometer/GNSS
Mechanical & Environmental
Package: compact LGA/SMD package (typical dimensions ~4 × 4 × 1 mm — verify exact package drawing before layout) Mounting: PCB-mounted with recommended land pattern per manufacturer footprint Operating temperature range: -40°C to +85°C (industrial), typical — consult manufacturer for extended ranges Storage temperature: -55°C to +125°C Shock and vibration: Designed to withstand typical consumer/industrial shock levels; refer to mechanical spec sheet for exact g ratings gyd-9e datasheet
Electrical Characteristics
Supply voltage: 1.8 V to 3.6 V (common nominal 3.3 V operation) Operating current: low-power standby and active modes (µA–mA range depending on mode and data rate) I/O logic levels: compatible with supply domain (1.8 V or 3.3 V) Power management: multiple power modes (sleep, standby, active), configurable to trade off power vs. bandwidth
Accelerometer
Axes: X, Y, Z Typical full-scale ranges: ±2 g, ±4 g, ±8 g, ±16 g (selectable) Sensitivity: specified in mg/LSB for each range Noise density: low noise for accurate low-dynamic measurements (refer to datasheet table) Bandwidth: programmable bandwidth via digital filters Zero-g offset and bias stability: specified in datasheet (temperature-dependent)
Gyroscope
Axes: X, Y, Z Typical full-scale ranges: ±250 °/s, ±500 °/s, ±1000 °/s, ±2000 °/s (selectable) Sensitivity: specified in °/s per LSB for each range Noise density: low rate noise suitable for stabilization and navigation tasks Bias stability and drift: temperature-dependent; on-chip temperature compensation provided Rate output update: configurable data rates up to several kHz (consult datasheet) GYD-9E Datasheet — Overview and Key Specifications The
Interfaces & Registers
Digital interfaces: I2C (standard/fast mode) and SPI (mode 0/3) — selectable Default I2C address: device-specific (check datasheet) Register map: control registers for power, ranges, filtering, interrupts, and self-test Data formats: raw accelerometer and gyroscope outputs typically 16-bit signed integers (two’s complement) FIFO: optional FIFO buffer to reduce host load and support burst reads Interrupt pins: data-ready, motion/detection, FIFO watermark, etc.
