TRX433-72
LoRA transceiver module for 433 MHz
The TRX433-72 is a low-cost LoRa transceiver module with the SX1261 radio chip. The module is suitable for point-to-point connection with LoRa modulation.
The radio module must be controlled by an external microcontroller.
Features
- LoRa radio transceiver for intelligent, flexible LoRa and LoRaWAN radio systems
- Very long radio range
- Very high sensitivity with very low receive current
- for applications with long battery life
- SPI interface
- User-friendly C library with many functions
- Swiss made: We develop, produce and test this product ourselves in-house.
