433M/315M Discrete ASK Transmitter Module (other frequencies need to be customized)
M-AF119M is a wireless module designed based on a high-performance superheterodyne wireless transmitter chip. It is a high-power, low-cost, small size, and coded (1527 million sets of learning codes) superheterodyne wireless transmitter module, which integrates cost-effective wireless data Transmitting chip and low-power MCU with excellent performance.
This wireless module has industry-standard transmission power and frequency stability, the data encoding rate is default 2K, transmitting cycle can be customized, and can be used with our low-power RF receiving module, which can replace the 1527 encoding remote control.
The transmitting working current is 8mA@12dBm. The high-power version can be customized. The transmitter chip adopts SOT23-6 package and supports 3 buttons (or pulse signal). To provide you the best wireless RF solution, the radio frequency communication protocol, transmission rate, carrier frequency, number of buttons, also can be customized according to your requirement.
