Module radio RFM69HCW
- Le VMA214 / RFM69HC est un module radio qui fonctionne dans les bandes ISM (Industrie, Science et Médecine) sans licence 315, 433, 868 et 915 MHz. Ce spectre de fréquences est destiné aux radios de faible puissance, à courte portée et sans licence. Idéal pour construire des réseaux sans fil à courte portée et à faible coût, des capteurs et d'actionneurs pour la domotique, l'éducation, etc.

The RFM69HCW transceiver module operates over a wide frequency range, including the 315, 433, 868 and 915 MHz license-free ISM (Industry Scientific and Medical) frequency bands. All major RF communication parameters are programmable and most can be set dynamically. The RFM69HCW is optimized for low power consumption while offering high RF output power and channelized operation.
This VMA214 RFM69HCW Radio Shield connects the RFM69HCW module to the appropriate lines on the Arduino. By using the RF69 Library, you can send and receive messages via standard 4-wire SPI interface. The library includes command structures for setting up anything from simple non-addressed point-to-point communication to fully addressed networks of clients and routers. Frequency can be set with 61Hz precision to any frequency from 240.0MHz to 960.0MHz.
The shield has on-board power regulation and level shifting, an external antenna via the I-Pex connector and additional jumpers to set the interface and digital communication pins on the Arduino.
