>The AS32-TTL-100 is a 100 mW industrial-grade, high-stability wireless data module operating at 433 MHz. The module adopts SX1278 core chip, extended spectrum LoRa transmission, TTL output, and is compatible with 3.3V and 5V I/O port voltage. The extended spectrum LORA makes the module have a longer communication distance. The operating frequency of the AS32 is 410 MHz to 441 MHz with a total of 32 channels.
1 Module size 23 X 43 mm (without antenna or SMA connector)
2 Device source All imported components from Japan, USA, Germany
3 Production craft lead-free packaging in electrostatic bag
4 Interface mode 1 X 7 X 2.54mm, plug-in packaging, universal board and DuPont line can be used
5 Working frequency 410-441MHz, 1MHz step by step, factory frequency: 433.0 MHz
6 Power supply voltage 2.5V-5.5V DC, meet a variety of system requirements. (If the voltage is less than 3.6V, the transmitting power will be reduced, which has little effect on the receiving performance)
7 Communication level Maximum 5.2V, the difference between the recommended voltage and the power supply voltage is less than 0.3V to reduce power consumption
8 Measured distance (3.0 VDC) Approximately 3000 m test conditions: sunny, open, maximum power, 5 dBi antenna gain, height over 2 m, air speed 2.4 KB
9 Transmit power Maximum 20 dBm, approx. 1 W, 4 levels adjustable (0-3), increase or decrease by approx. 3 dBm at each level.
10 Air rate 6 adjustable levels (0.3, 1.2, 2.4, 4.8, 9.6, 19.2 Kbps)
11 Sleep current 1.5 µA (MD1 = 1, MD0 = 1)
12 Current transmission 110 mA at 1 W (voltage 5 V)
13 Receive current 18 mA (mode 0, mode 1), minimum about 30 µA (mode 2 + 2 s wake-up)
14 Communication Interface Serial UART port, 8N1, 8E1, 8O1, 1200 to 115200, total 8 baud rates
15 Drivers UART serial port can be configured in push-pull/pull-up, open-drana modes
16 Transmission length Internal 256 byte FIFO ring cache, internal automatic subcontracting. Some combinations of air and data rates can send packets of infinite length.
17 Receive length Internal ring cache 256 byte FIFO, internal automatic subcontracting. Some combinations of air speed and data rate can send packets of infinite length.
18 Module address 65536 customizable addresses (easy network connection, support broadcast and fixed transmission)
19 RSSI support Built-in intelligent processing
20 Receiving sensitivity -130 dBm at 2.4 Kbps (receiving sensitivity has nothing to do with the serial port baud rate and latency)
21 Antenna type SMA antenna/spring antenna
22 Operating temperature -40 ℃ to +85 ℃
23 Operating humidity Relative humidity 10%-90%, non-condensing
24 Storage temperature from -40 ℃ to +125 ℃
