DESCRIPTION This Wireling features the high performance and low power Bosch BMA250 3-axis accelerometer. The BMA250 allows measurement of accelerations in three perpendicular axes and thus senses tilt, motion, shock, and vibration in your projects. There is also an integrated temperature sensor built-in. New to Wirelings? Check out the Wireling Overview! Note* 5-Pin Wireling cables not included and sold separately. TECH SPECS Bosch BMA250 Accelerometer Specs 3-axis (X, Y & Z) Digital resolution: 10bit Resolution: 3.9mg Measurement ranges: +-2g, +-4g, +-8g, +-16g Sensitivity: 2g: 256LSB/g, 4g: 128LSB/g, 8g: 64LSB/g, 16g: 32LSB/g Zero-g offset (over lifetime): +-80mg Bandwidths: 1000Hz - 8Hz Low Power: 139uA @2kHz data rate Built-in temperature sensor TinyDuino Power Requirements Voltage: 3.0V - 5.5V Current: 139uA (Normal Mode) Pins Used A5/SCL - I2C Serial Clock line A4/SDA - I2C Serial Data line Dimensions 10mm x 10mm (.394 inches x .394 inches) Max Height (from the lower bottom of Wireling to upper top Wireling Connector): 3.70mm (0.15 inches) Weight: 1 gram (.04 ounces) NOTES You can also use this board without the TinyDuino – modifying the connecting cable by removing the opposite connector and stripping/tinning the wires, you can solder the connector cable to any other microcontroller board of your choice!
