RF-T4 Operating voltage
Power for the RF-T4 board is marked 5.0 Vdc. The postings indicate it can operate to 10.0 Vdc. The PT2272 datasheet indicates operational voltage up to 15.0 Vdc, and the LM358 is not an issue. I would like to power the device from well controlled automotive power. Is there another voltage limitation that is not so obvious?
