What are the ROVL power requirements

ROVL Mk II

Receiver-in power: Note: The receiver is designed to allow operation from a laptop USB port using a serial-to-USB adapter.

5V to 16V DC ~1.5 Watt

Transmitter V-in power: Note: Power supplies 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.

4.5V to 28V DC 1.4W @ 5V 1.6W @ 28V

Serial Comms Voltage Levels

3.3V TTL or 5V TTL, auto sense

ROVL Mk III

Transceiver V-in power (see note)

5 to 16V   2.5W average, 3.5W peak @5V DC   2.1W average, 3.3W peak @12V DC

Transponder V-in power (see note)

4.5V to 28V   1.7W average 2.9W peak @5V DC   1.3W average, 4.1W peak @16V DC

Serial Comms Voltage Levels

3.3V TTL or 5V TTL, auto sense

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.
