EBYTE E220P-400T22S PA+LNA LLCC68 long-distance stable transmission 433mhz rf transceiver module

E220P-400T22S LoRa spread spectrum technology wireless transmission monitoring [IC]：LLCC68 [Frequency]：410.125~493.125MHz [Power]：22dBm [Distance]：7km [Size]：16*26mm [Product weight]：2g±0.1g [Introduction]：E220P-400T22S adopts the new generation of LoRa spread spectrum technology, a wireless serial port module (UART) designed based on LLCC68 RF chip solution, and a built-in LNA, active temperature compensated crystal oscillator and receiving limiter in the wireless module. Under ideal conditions, the communication distance can reach 7km (5.6km for E220-400T22S), with stronger anti-interference ability and longer receiving distance. It supports functions such as air wake-up, carrier monitoring, communication key, and sub-packet length setting, and can provide customized development services.
