Note: Power supplies for both units must be able to supply burst currents to prevent drop-out and erratic operation. While the transmitter will work with a low impedance 5V supply we recommend using 9V or higher, unless you know how to figure out if your 5V power supply is low-enough impedance.
Note: Resolution ≠Accuracy!
