[Packaging method]: SMD

[Product size]: 16*26mm

[Introduction]:E34-2G4H20SX product is a wireless data transmission module developed by Ebyte, which works in the 2.4-2.518GHz frequency band, half-duplex, TTL level output, compatible with 3.3V, 5V IO port voltage, and uses the serial port for data transmission and reception. The wireless module has the characteristics of automatic frequency hopping, strong anti-interference ability, high transmission rate and low delay.
