I came across these very cool 2.4 GHz transceiver modules and I couldn't pass them up. They have 200mW output, frequency hopping spread spectrum at 2.4 GHz. With a 3dBi gain antenna, that's 400mW EIRP!
The transceivers have asynchronous 5V, TTL level serial interface for host communications at baud rates from 110 bps to 288,000 bps. The Host supplies system data for transmission. Configuration data is stored in an on-board EEPROM. All frequency hopping, synchronization, and RF system data transmission/reception is performed by the transceiver itself.
One of the coolest feature I think of these transceivers is built in RSSI (Received Signal Strength indicator), on pin 13. This pin has a voltage from 2v to 5 volts, indicating the input power of the remote transceiver to that transceiver in dBm. You can read this directly with a pulldown resister and Arduino analog pin.
The transceivers can be used as a direct serial cable replacement – requiring no special Host software for operation. They also feature a number of On-the-Fly Control Commands providing the OEM Host with a very versatile interface for any situation.
You will need an MMCX pigtail whichever antenna you intend to use. I have a two MMCX to TNC pigtails that I will throw in for free with the first two that sell.
I have the .2mm pin headers for these and I will ship one with every transceiver I ship
