Lora Transceiver 5V RF Wireless Receiver Module 915MHz UART Long Range Communication Data Converter
Product Description
A39-T900A30D1a is newly developed UART wireless data transmision product. It works between the frequency 850~931MHz. With the power of 1W(30dBm) and LoRa spread spectrum chip design and development, LORA spread spectrum modulation, data can transmit as long as 10km in open space.
Compared with our classic wireless unit, it performs with more functions,such as Data Relay, Data Polling from Master node, Data Reporting from Slave node,Remote configuration etc. All these functons enable uses have more options in real application.
For now, A39-T900A30D1a has been used in some specific iot industry and applications, such as Photovoltaic energy meter, alarm system, power station water level meter, parking sensor system, LED screen control, etc. Need more details and datasheet, Please contact us immediately.
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℃ |
