Features:
【High-Efficiency Wireless Transmission】Features an radio transmitter module utilising the latest microchiped technology, delivering superior frequency stability compared to conventional capacitive three-point oscillators.
【Simple 】The module employs mount devices (SMDs), requiring users to solder the power supply and antenna themselves, catering to enthusiasts' hands-on requirements.
【Multi-Scenario Applications】High-sensitivity microphone type suits wireless recording, remote monitoring, and maternal-infant care scenarios.
【Energy-Efficient Long Battery service】Operating current is merely 9mA (tested at 3V), featuring low power consumption suitable for extended continuous use.
【Flexible Frequency Adjustment】Frequency can be easily adjusted using a small screwdriver via the trimming capacitor on the circuit board, adapting to the reception requirements of different devices .
