The Inertia Measurement Unit Combo Board with the high-precision ADXL203. The ADXL203 sensor is a much higher precision sensor with a range of +/-1.5g. This small PCB board incorporates the Analog MEMs gyroscope and accelerometer in a tight footprint. The IMU board uses a standard .1" header and includes all outputs from both the ADXRS Gyro and ADXL Accelerometer ICs.

We created this board because of the retirement of the Tokin CG-16D piezoelectric sensors. These cheap sensors are now becoming obsolete and difficult to find. The ADXRS sensors from Analog are a great substitute but hobbyists were hindered by the BGA package. By combining the ADXRS with the ADXL sensors, the IMU board enables students and hobbyists to easily incorporate yaw and tilt measurements into their projects or robots.

Board comes fully assembled and tested with ADXL203 and ADXRS300. Units come as shown without headers installed. We recommend right-angle break away headers, straight pin headers, or wire up your own cable!

Dimensions: 0.75"x1.0" (20x25.4mm)
Weight: 3g with header
