Product Introduction

AS32-TTL-100 SX1278/SX1276 wireless module 433mhz

Specifications

No. Parameter Name Parameter values details
1 Module Size 23 X 43mm (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 X 7 X 2.54 mm, plug in 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 smaller 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, higher than 2m, 2.4K air rate
9 Transmission power Maximum 20dBm, about 100mW, 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@100 mW (voltage 5V)
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.
