Product Overview
Description
Lora Sx1278 Iot Rf Tx Rx 433mhz Modbus And Module Long Range Wireless Transmitter Receiver
AS32-TTL-100 is a 100 mW industrial-grade wireless data transmission module with high stability working on 433MHz frequency. The module uses SX1278 main chip, LoRa spread spectrum transmission, TTL level output, compatible with 3.3V and 5V IO port voltage. LORA spread spectrum makes the module have a longer communication distance. AS32 operating frequency is 410MHz to 441MHz with a total of 32 channels.
Dimension
Specifications
| No. | Parameter Name | Parameter values details |
|---|---|---|
| 1 | Module Size | 23 X 43mm (not including an 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 | 1 X 7 X 2.54 mm, plugin packaging, you can use the universal board and DuPont line |
| 5 | Operating frequency | 410 to 441MHz, 1MHz step by step, factory default: 433.0MHz |
| 6 | Supply Voltage | 2.5V-5.5VDC, meet a variety of system requirements. ( if the voltage is less than 3.6V, the transmission power will decline, which has little impact on the receiving performance) |
| 7 | Communication level | Maximum 5.2V, The difference between the recommended and supply voltage is less than 0.3V to reduce power consumption |
| 8 | Measured distance (3.0VDC) | About 3000m test conditions: sunny, open, the maximum power, Antenna gains 5dBi, height greater than 2m, 2.4K air rate |
| 9 | Transmission power | Maximum 20dBm, about 1W, 4levels adjustable (0-3), increase or deduct about 3dBm each level. |
| 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 | 110mA@1W (voltage5V) |
| 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 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 | -130dbm at 2.4Kbps (receiving sensitivity has nothing to do with serial port baud rate and delay time) |
| 21 | Antenna type | SMA antenna/spring antenna |
| 22 | Operation temperature | -40℃ to +85℃ |
| 23 | Operation humidity | 10%-90% relative humidity, no condensation |
| 24 | Storage temperature | -40℃ to +125℃ |
Pin Definition
| Pin No. | Name | Pin direction | Pin application |
|---|---|---|---|
| 1 | MD0 | Input (very weak pull up) | Cooperates with MD1 to decide 4 kinds of work modes, cannot be floated |
| 2 | MD1 | Input (very weak pull up) | Cooperates with MD0 to decide 4 kinds of work modes, cannot be floated |
| 3 | RXD | 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 and can be configured as an open-drain output, or push-pull output, see parameter settings. |
| 6 | VCC | 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 line, connected to the power supply reference ground. |
