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) |
