Wireless Radio Interface for Raspberry Pi
Converts wireless signals to serial input and output, and vice versa. When connected to a Raspberry Pi or Orange Pi 2 W, it acts as an IoT hub for virtually unlimited JemRF wireless devices.
The IoT Receiver is compatible with both the older RF2 and the newer RF4 devices.
Features:
- Simple plug-and-go radio module for the Raspberry Pi
- Support for Raspberry Pi 3/4 or Zero W models
- Communicates with our radio modules
- TTL UART (/dev/ttySerial0 on the Raspberry Pi)
- Fits inside popular Raspberry Pi cases like the Stealth Case and PiBow
- Default 9600 Baud
-
Fitted with wire whip antennae
- Provides RSSI (Received Signal Strength Indicator) to show signal strength for each sensor.
Standard
- 10-pin header that fits all Raspberry Pi models. When mounted on the 40-pin Raspberry Pi, the first 10 pins are not accessible because they are used by the radio.
The color of the board may vary from the picture.

Technical Specs:
- All devices are based on the high-performance RF transceiver using the market-leading CC1100 SOC.
- A wide operating voltage range of 2-3.6V suits the devices for battery power.
- Current consumption: RX: 16.2 mA, TX: 15.2 mA. Deep Sleep: 0.005Ma (0.5 µA).
- Up to 1KM line of sight. Short-range (30M) penetration of walls and floors.
- 128-bit AES encryption security.
- Driverless installation.
- All the devices are highly configurable through the serial port or over the air using the LLAP messaging protocol specified in the manual.
- The base station communicates through a serial port (TTL UART).
- Communicates in clear ASCII text, making it very easy to exchange data between devices over the air.
- Supports point-to-point, point-to-multi-point, multi-point-to-point and multi-point-to-multi-point.
- A virtually unlimited number of devices can be deployed—99,999 Personal Area Network IDs, 10 channels per frequency, and 7,744 Device IDs per network.
- Super-low power consumption allows devices to run on a coin cell battery for extended periods (up to 1 year, depending on transmission rates).
- Supports six frequencies (433 MHZ, 915 MHz (default US & Canada), 868.3 MHZ (default Europe), 868 MHz, 903 MHz, 315 MHz)
- 10 channels per frequency.
- 4 pins for communicating with external microcontrollers like Raspberry Pi and Arduino: Tx, Rx, GND, 3V3.
- Uses pins 1,6,8 and 10 (PWR, GND, TX, RX, respectively) on Raspberry Pi
