Industrial long distance 10km SX1278 wireless transceiver module mini wireless serial control. 410-441MHz(default 433MHz), 1W, industrial-grade wireless data transmission module. LORA spread spectrum modulation, high anti-interference and long distance transmission(up to 10km). Easy Operation: four working modes and can be switched freely during application. Ultra Low Power: Ideal for low power applications,such as automobile detection,flow detection, screen control, etc. Electronical Parameters No. Parameters Value and details 1 Module Size 23 X 43mm (not including antenna or SMA junction) 2 Module Weight 20g without an antenna 3 Production craft Lead-free, electrostatic bag packaging 4 Interface mode 1 X 7 X 2.54 mm, plug-in packaging, universal board , and DuPont line can be used 5 Operating frequency 410 to 441MHz, factory default: 433.0MHz 6 Supply Voltage 2.5V-5.5VDC, meet a variety of system requirements 7 Communication level Maximum 5.2V 8 Measured distance (3.0VDC) Up to 10km 9 Transmission power Maximum 30dBm, about 1W, 4 levels adjustable (0-3) 10 Air rate 6 levels adjustable (0.3, 1.2, 2.4, 4.8, 9.6, 19.2Kbps) 11 Sleep current 1.5uA (MD1 =1, MD0 = 1) 12 Transmitting current 520mA@1W (voltage 5V) 13 Receiving current 18mA (mode 0, mode 1), minimum about 30uA (mode 2 + 2s wake-up) 14 Communication Interface UART serial port, 8N1, 8E1, 8O1, from 1200 to 115200 15 Driving means UART serial port can be set to push-pull / pull-up, open-drain 16 Transmitting length Internal ring FIFO cache 256 bytes 17 Receiving length Internal ring FIFO cache 256 bytes 18 Module address 65536 configurable addresses 19 RSSI support Built-in intelligent processing 20 Receiving sensitivity -130dbm at 2.4Kbps 21 Antenna type SMA antenna / spring antenna 22 Operation temperature -40°C to +85°C 23 Operation humidity 10%-90% relative humidity, no condensation 24 Storage temperature -40°C to +125°C Pin Specification Pin No. Name Pin Direction Pin Application 1 MD0 Input (very weak pull up) Cooperates with MD1 to decide 4 kinds of work modes, which cannot be floated 2 MD1 Input (very weak pull up) Cooperates with MD0 to decide 4 kinds of work modes, cannot be floated 3 RDX Input TTL UART inputs, connected to the external TXD output pin. It can be configured as open-drain or pull-up input, see parameter setting 4 TXD Output TTL UART outputs, connected to the external RXD input pin. It can be configured as open-drain or pull-up output, see parameter setting 5 AUX Output Used to indicate the working status of the module, the user wakes up the external MCU; during the initial power-on self-test period, it outputs low. It can be configured as an open-drain output, or push-pull output, see parameter settings 6 VCC Power Input Power input, power supply 2.5-5.5V (Note: if it is less than 4.5V, the output power will decline, but the impact on the reception performance is very small.) 7 GND Ground Ground line, connected to the power supply reference ground.
