ADXL335 3-axis Accelerometer (GY-61) [S057]

https://www.youtube.com/watch?v=VhsJ0hoZzxo

*GitHub : https://github.com/rdiot/rdiot-s057.git

* Specs

This is a very low cost break out module for the ADXL335 tripple axis accelerometer. This module includes optional header pins and provides easy access to the X, Y and Z axis analogue outputs from the accelerometer. 

It is capable of sensing forces up to 3g in all axis. A 3.3V on-board regulator is also provided allowing the module to be powered from a 3.3 to 5V power supply source.

Model number: HCMODU0070

Supply Range: 3V ~ 5V

3 Axis sensing

Full scale range: +/-3g

Sensitivity: 300mV/g (Typ)

Pinout, schematic and datasheet available after purchase.
