[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.

20 M0 Input (very weak pull-up) Cooperate with M1 to determine the 4 working modes of the module (cannot be left floating, can be grounded if not used)
21M1 Input (very weak pull-up) Cooperate with M0 to determine the 4 working modes of the module (cannot be left floating, can be grounded if not used)
22RXD Input TTL serial port input, connected to the external TXD output pin;
23TXD output TTL serial port output, connected to the external RXD output pin;
24TO output Used to indicate the working status of the module; the user wakes up the external MCU and outputs low level during power-on self-test initialization; (can be left floating)
25 VCC - Module power supply positive reference, voltage range: 2.3~5.5V DC
26 GND - Module ground wire
