Sale is for TWO units high power modules plus usb ttl adapter , two antennas and cables. Complete TRANSPARENT SERIAL link KIT. This modules are a transparent serial wireless 2.4GHz link. Means you can transmit UART serial TTL data from one point to other or others in broadcast. Modules have individual address so you can trasmitt to one or many on same ID. Retransmit if failure, default up to 100 retries. Update multiple arduinos at same time. Create Uart serial wireless network. Connect TX, RX and power and module is ready. WiFi band usage.
Simply connect a TTL serial interface to a transmitter and receiver module and the modules will transparently transmit your data over a 2.4GHz signal at a range of up to pratical 400 meters or much more with high gain annetna Up to Km's connection. The module can also be placed into a configuration (AT) mode and using simple ASCII 'AT' commands sent via its serial port its default parameters can be changed. This includes changing its frequency to one of 80 channels or its two byte ID which allows a theoretical 65536 modules to communicate with each other. To try and reduce errors caused by poor reception an automatic retry system is enabled (defaults to 100 retries) which will repeatedly resend a data packet a fixed number of times.
VDD: 3.3V or 5V power supply
TXD: serial port output, Arduino or USB to serial port RXD
RXD: serial port input, Arduino or USB to serial port TXD
CMD: Enter PIN AT mode, active low level;
GREAT APPLICATION example: COMMANDS OVER THE AIR to control any IO's, timmers, PWM analog from any arduino compactible board. Just create commands as you need and function handler, commands will be received by wireless and reach the target function or task
Send defined command by serial wireless and remote arduino/arduinos will do it. Create more functions for more commands or tasks. Check out: serial commands example
Download Arduno library here: AT command style library
Now you can control any arduino IO's wirelessly real time. Any microcontroller with TX, RX serial will work for this wireless modules.
See example serial commands over the air network diagram here: basic diagram multiple modules communication
