Product Description
AS13B-TTL is a 100mW industrial wireless data transceiver with high stability, operates at 433MHz. The module is designed and developed using imported RF chip SI4438 from Silicon Labs. The module features small size,high sensitivity, long transmission distance, high communication speed, etc., and the function of automatically completing communication protocol conversion and data transcending control can be realized internally. The module has two operating states and can be freely switched during operation.
Electric Parameterel
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   1 * 6 * 2.54 mm, plug in packaging, you can use the universal board and DuPont line
5 Operating frequency   425 - 450.5MHz, 0.1MHz step by step, factory default: 433MHz
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 3.6V, The difference between the recommended and supply voltage is less            than 0.7V to reduce power consumption
8 Measured distance (3.0VDC)   About 2200m test conditions: sunny, open, the maximum power, Antenna gains 5dBi,            higher than 2m, 1K air rate
9 Transmission power   Maximum 20dBm, about 100mW, 4levels adjustable (0-3), increase or deduct about              3dBm each level.
10 Air rate

  8 levels adjustable(1kbps,2kbps,4kbps,10kbps,15kbps,20kbps,40kbps,100kbps)

11 Transmitting current   82mA@100mW (voltage 5V)
12 Receiving current   16mA
13 Communication Interface   UART serial port, 8N1, 8E1, 8O1, from 1200 to 115200 a total of 8 baud rates
14 Driving means   UART serial port can be set to push-pull / pull-up, open-drain
15 Transmitting length   Internal ring fifo cache 256 bytes, the internal automatic subcontract sending. Some            airspeed and baud rate combinations can send infinite length packets.
16 Receiving length   Internal ring fifo cache 256 bytes, the internal automatic subcontract sending. Some            airspeed and baud rate combinations can send infinite length packets.
17 Module address   65536 configurable addresses (easy to network, support for broadcast and fixed                  transmission)
18 RSSI support   Built-in intelligent processing
19 Receiving sensitivity   -124dbm @ 1Kbps (receiving sensitivity has nothing to do with serial port baud rate              and delay time)
20 Antenna type   SMA antenna 
21 Operation temperature   -40℃ to +85℃
22 Operation humidity   10%-90% relative humidity, no condensation
23 Storage temperature   -40℃ to +125℃
