  • Mostly 5v Tolerant

    posted by chuck0001

    This sensor is compatible with the Arduino environment. 1. onboard 3.3v regulator2. SCL, SDA 5v tolerant with onboard level shifter.3. SA0 connected to ground via resistor, Connect to pin 2(3.3v output) to change I2C address from 0x1C to 0x1D4. came with 2 sets of 0.100in pins, straight and 90degrees.
    The manufacture could improve the design by adding 5v level shifters to the INT1 and INT2 pins.Dalmir da Silva has created an Arduino compatible driver at https://github.com/dalmirdasilva/ArduinoAccelerometerDriver
    The Freescale MMA8452 is a very nice and inexpensive 3 axis accelerometer. You can interface it to an Arduino board using only 1 exclusive pin, the interrupt pin. By using the I2C communication built into the Adruino five wires are all that are necessary for complete function. Power(5V), Ground, SCL, SDA, INT. And if you do a little software sharing you can even share the INT pin by configuring Open Collector drive and electrically or'ing output of multible I2C devices.
  • Works as it should

    posted by cmichal

    This is a nice board with a 3-axis accelerometer, ADXL345, and 3-axis magnetic field sensor, HMC5883L. The board has has a 3.3V regulator so it can be powered from 5V and interfaced directly to a 5V microcontroller. It does what it is supposed to do.
    The ADXL345 uses the alternate address (0x53) rather than 0x1D.Arduino libraries to access the two chips are available at:https://www.loveelectronics.co.uk/Tutorials/12/adxl345-accelerometer-arduino-tutorialhttps://www.loveelectronics.co.uk/Tutorials/8/hmc5883l-tutorial-and-arduino-libraryThe code examples there worked for me, though the call to set-up the ADXL345 needed to specify the correct address (0x53) as the default doesn't match the board. The ADXL345 code example sets the sensor to the 2g range, which was no good for me - one of the axes has a ~4g offset so it was simply pegged on the 2g range.Both sensors require offset and scale calibration before they are useful.
    Good value for a simple board to access these two chips. The sensors themselves are not exactly plug and play though - calibration is required before they are useful.
  • Affordable motion processing sensor

    MPU-6050 is a serious little piece of motion processing tech. It provides digital-output of 6 or 9-axis MotionFusion data in rotation matrix, quaternion, Euler Angle, or raw data format. Can also measure teperature. Great to have one at this price.
    Great gadget with many applications. I will use it in autonomous robot. You have to solder the pins, but at least you can choose which one is better for you, straight or angled, both are provided in package.
    Top price for top gadget! Recommendable.
