I'm thinking of making the antenna a dipole and suddenly I'm stumbled whether to make the other leg the circuit GND or positive rail. The supply voltage is 3VDC and the RF signal is about 1.8Vpp 100MHz. Part of me thinks that the main antenna port will be floating somewhere between GND and VCC. WebFeb 24, 2014 · But you need to apply the Arduino 5V to the VCC of the sensor breakout board. Since there is a voltage regulator for the MPU-6050, using 3.3V would result in a voltage that is too low for the I2C bus. Beside the AD0, the rest is simple: Arduino 5V -> all Vcc of all MPU-6050 breakout boards. Arduino GND -> all GND. ray ban scratch resistant lenses
