[Introduction]：E22-230T30S est un module de port série sans fil (UART) basé sur la solution LoRa de SEMTECH. Il dispose de plusieurs modes de transmission, d'une bande de fréquence de fonctionnement (220,125 MHz ~ 236,125 MHz), d'une technologie à spectre étalé LoRa, d'une sortie de niveau TTL et est compatible avec les tensions des ports IO de 3,3 V et 5 V.

Serial Number	pin	Pin direction	Remark
1	GND	-	Module ground wire
2	VCC	-	Module power supply positive reference, voltage range: 3.3～5.5V DC
3	TO	Output	Used to indicate the module's operating status; outputs a low level during the power-on self-test initialization period when the user wakes up the external MCU ; (can be left floating).
4	TXD	Output	TTL serial port output, connected to the external RXD input pin;
5	RXD	Input	TTL serial port input, connected to the external TXD output pin;
6	M1	Input (very weak pull-up)	In conjunction with M0, it determines the module's four operating modes (it cannot be left floating; if not in use, it can be grounded).
7	M0	Input (very weak pull-up)	In conjunction with M1, it determines the module's four operating modes (it cannot be left floating; if not in use, it can be grounded).
11	ON	Output	Antenna interface (high-frequency signal output, 50 ohm characteristic impedance)
12	GND	-	Fixed
13	GND	-	Fixed
14	GND	-	Fixed
18	NC	-	Empty foot
19	NC	-	Empty foot
20	NC	-	Empty foot
21	NC	-	Empty foot
22	RESET	Input	The reset pin during program loading (floating, no user connection required).
23	GND	Input	Ground pin during program loading (floating, no user connection required).
24	NC	-	Empty foot
