The UHF radio utilizes a half-duplex architecture with high-performance low power consumption transceiver which is controlled by a dedicated ARM Cortex-M4 MCU. The radio uses ultra-high frequency band (UHF) that is programmable in 395 to 440 MHz range.

The module supports GFSK2 modulation and 2400, 4800 and 9600 bps as bit rates. Modulation is configured to be ¼ of symbol rate and consequently, it is MSK modulation.
