- Control mode: TTL 0/1.8~5V level (Or, automatic detection of the input power can be used to achieve automatic transmission and reception. However, the transmission delay will be slightly increased, but it can still be used normally. EN high level(1.5~5.5V): Power amplifier is in transmitting mode,but receiving is off. EN low level (0~1.0V) : Receiving status, but transmitting is off (power amplifier static current is less than 0.17A with low-noise amplifier )
- Working temperature: -25~+85℃
- Temperature protection: If the module temperature reaches 105 ± 5 degrees, the transmission will be automatically shut down and only reception will be enabled.
- Supply voltage: 12V(10 - 16V ), the higher the voltage, the higher the output performance)
