Lora Transceiver 5V RF Wireless Receiver Module 915MHz UART Long Range Communication Data Converter Electric Parameter No. Parameter Name Parameter values details 1 Module Size 20 * 36mm (not including antenna or SMA junction) 2 Source of the devices All imported components from Japan, USA, Germany 3 Production craft lead-free, electrostatic bag packaging 4 Interface mode DIP package, you can use the universal board and DuPont line 5 Operating frequency 850 - 931MHz, 1MHz step by step, factory default: 915MHz 6 Supply Voltage 2.0V-5.5VDC, meet a variety of system requirements. ( if the voltage is smaller than 3.6V, the transmission power will decline, which has little impact on the receiving performance) 7 Communication level Maximum 5.0V, The difference between the recommended and supply voltage is less than 0.7V to reduce power consumption 8 Measured distance (3.0VDC) About 10,000m test conditions: sunny, open, the maximum power, Antenna gains 5dBi, higher than 2m, 1 K air rate 9 Transmission power Maximum 30dBm, about 1W, 4levels adjustable (0-3), increase or deduct about 3dBm each level. 10 Air rate 8 levels adjustable(1.2kbps,2.4kbps,4.8kbps,9.6kbps,19.2kbps,38.4kbps,62.5kbps) 11 Sleep current 3uA (MD1 =1, MD0 = 1) 12 Transmitting current 550mA@100mW (voltage 5V) 13 Receiving current 10mA (mode 0, mode 1), minimum about 30uA (mode 2 + 2s wake up) 14 Communication Interface UART serial port, 8N1 or 7N1, 8E1, 8O1, from 1200 to 115200 a total of 8 baud rates 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, the internal automatic subcontract sending. Some airspeed and baud rate combinations can send infinite length packets. 17 Receiving length Internal ring fifo cache 256 bytes, the internal automatic subcontract sending. Some airspeed and baud rate combinations can send infinite length packets. 18 Module address 65536 configurable addresses (easy to network, support for broadcast and fixed transmission) 19 RSSI support Built-in intelligent processing 20 Receiving sensitivity -140dbm @ 1Kbps (receiving sensitivity has nothing to do with serial port baud rate and delay time) 21 Antenna type SMA antenna 22 Operation temperature -40℃ to +85℃ 23 Operation humidity 10%-90% relative humidity, no condensation 24 Storage temperature -40℃ to +125℃ PIN Connection Features
