Description
The radio module with the RFM69HCW system is designed to work with the Raspberry Pi. It operates at 433 MHz (sub-GHz) and can transmit data up to 500 m with a built-in antenna, and even up to 5 km with an external directional antenna. Modules perform packetization, error correction, and can also retransmit data automatically. The user has an OLED display with a resolution of 128x32 pixels and three buttons, so you can easily create a user interface or a simple module for sending text messages. The board connects to the minicomputer via a 40-pin GPIO connector, and communication takes place via the SPI (radio module) and I2C (display) interface. Full documentation with examples is available on the product page.
Features
- Radio module RFM69HCW
- CircuitPython Library
- The module is based on SX1231 with an SPI interface
- Output power +13 to +20 dBm to 100 mW (configurable via software)
- Current consumption from 50mA (+13 dBm) to 150mA (+ 20dBm) for transmission, ~ 30mA during active listening
- Range approx. 500 meters, depending on obstacles, antenna and power output
- Encryption with AES-128
- Uses the ISM band without a license
- U.FL radio connector (mounted) and SMA (soldering pads)
- Display type: OLED
- Resolution: 128x32 px
- Display interface: I2C
- Display color: black, white
