Ebyte E22-400T37S SX1262 433/470MHz 5W high power Relay networking LoRa wireless module

[Chip solution]: SX1268

[Transmission power]:37dBm

[Communication distance]: 25km

[Product size]: 50*30.9mm

[Introduction]:E22-400T37S is a new generation of LoRa wireless module based on SX1268 radio frequency chip wireless serial port module (UART), with a variety of transmission methods ,working in (410.125~493.125MHz)frequency band (default 433.125MHz), LoRa spread spectrum technology,TTL Level output, support 4 5 V - 15V supply voltage

E22-400T37S

Note: The module must be connected to a 50 ohm impedance antenna when sending, and sending without load may cause permanent damage to the module ! !
