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℃ |
