SA618F30-FD full-duplex wireless data transmission module supports 8-way concurrent transmission

SA618F30-FD full-duplex wireless data transmission module supports 8-way concurrent transmission

The SA618F30-FD is a highly integrated, cost-effective, high-power 8-channel full-duplex data transmission module. It features a built-in high-speed micro-controller, high-performance RF transceiver chip, and RF power amplifier. The module provides a standard serial port for communication, enabling easy and quick parameter settings and control of the transmit/receive functions. Users can achieve data transmission simply by connecting the module to the serial port. Its ultra-compact size allows for easy and fast integration into various handheld devices, enhancing the overall performance of terminal products, making this module widely applicable.

SA618F30-FD is an 8-way full-duplex wireless data communication module that can achieve up to 8 transmitters transmitting simultaneously without interfering with each other. It is designed for scenarios where multiple transmitters operate concurrently in complex environments, minimizing the likelihood of re-transmissions and significantly reducing interference and the chances of being interfered with. The combination of LoRa modulation with 1W output power, along with its low-power design for receiving and sleep modes, makes it ideal for long-distance wireless IoT applications.

Pin NO.	Pin name	I/O	Description
1	TXLED	O	Transmitting indicator, connected with external led, turn on by low level output when data is transmitting, (suggest 1K ohm resistor for current limitation)
2	RESET	I	Module reset pin: Pulling it low for more than 5 ms will reset the module
3,6,10,12,15,19	GND		Connect to the power supply ground
4，5，7，8	NC
9	RESERVED		Module test pin: Leave unconnected (floating) for users
11	+3.3VOUT		3.3V output, capable of driving an external load of up to 50mA
13	ANT		RF signal output, connect to a 50-ohm antenna
14	VCC		Connect to the positive power supply (external 3.3V to 5.5V)
16,17,18,20,21	NC
22	TXD	O	Module serial port transmit pin (voltage 0-3.3V)
23	RXD	I	Module serial port receive pin (voltage 0-3.3V)
24	NC
25	RXLED	O	External receive indicator light: Lights up on low level, normal high level output (requires an external current-limiting resistor of approximately 1K ohms)
26	CS	I	Module sleep pin: High level for operation, low level for sleep.Internally pulled up, defaults to high level。
