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 and can receive messages from either without any configuration changes.
Features:
- Simple plug-and-go radio module for the Raspberry Pi
- Support for Raspberry Pi 3/4, Pi Zero W, or Orange Pi 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
