... The RX2A module is a single conversion FM superhet receiver capable of handling data rates 64kbps. It will operate from a supply of 2.7V to 16V and draws 10mA when receiving. The RX2A features a fast power-up time for effective duty cycle power saving and a signal strength (RSSI) output with 60dB of range ...

... Power supply requirement The standard TX2A and the RX2A modules incorporate a built-in regulator which delivers a constant 2.8V to the module circuitry when the external supply voltage is 2.85V or greater, with 40dB or more of supply ripple rejection. This ensures constant performance up to the maximum permitted supply rail and removes the need for external supply decoupling except in cases where the supply rail is extremely poor (ripple/noise content > ...
