I got this MAG3110 magnetometer on Ebay, it came on a small break out board. This is not a sensor you want to solder by hand, it comes in a tiny 10 pin DFN package. The MAG3110 is a three axis digital magnetometer made by Freescale. The readings of a magnetometer can be used to [...]
I have been playing with my self built Arduino’s the last weeks. One of my designs is a small (5x5cm) board with an ATmega328P-PU and a header for a nRF24L01 wireless module. I named it the Bajduino 328RF24 Since the nRF24L01 modules work at 3,3V I decided to let the ATmega run @ 3,3V. I [...]
Some time ago I bought a cheap 9DOF board on Ebay. The board has 3 sensors, an ADXL345 accelerometer, HMC5883L magnetometer and an ITG3200 gyroscope. All 3 sensors are of the digital kind and use the I2C bus to communicate. These sensors need a voltage of 3,3V to work, luckily the board has an onboard [...]
