Description
Wireless module operating at 433 MHz at a range of up to 1000 meters. It is powered from 3.2 V to 5.5 V. It communicates via UART interface (RX, TX), e.g. fromArduino. There is an antenna included in the set, which should be soldered to the ANT output. The system also has a u.FL socket for connectingan external antenna with an adapter.The leads are holes for 2.54 mmgoldpinrasterconnectors, which should be purchased separately.

Connection
The system communicates through a standard UART serial interface. The description of the outputs is given in the table:
| Pin | Description |
|---|---|
| SET | Pin to change module settings, pulled up to VCC by default via 10 kΩ resistor. |
| TXD | Serial communication - transmitter. |
| RXD | Serial communication - receiver. |
| GND | The weight of the system. |
| VCC | Supply voltage from 3.2 V to 5.5 V. |
