This is an Arduino wireless programming kit which consists of USB wireless transmitter module and wireless receiver module. There is the MCU on board with built-in encoding and decoding code and it is easy to implement wireless uploading sketch.
USB wireless transmitter module connects to the computer, and you need to install the CH340 driver. The wireless receiver module should be connected to Arduino board.
You can set the ID number, working frequency and baud rate of the module through AT commands, and the modules who have the same ID number and operating frequency can communicate directly with each other.
Note: Transparent transmission baud rate should correspond with the Arduino board, such as baud rate of Arduino UNO R3 is 115200bps, and Pro Mini is 57800bps. Both USB transmitter module and receiver module should be set this baud rate.
- Working voltage: 3.2 - 5.2VDC
- Working Current: 21mA(MAX)
- Working Frequency: 2478MHz (default), 2400MHz - 2527MHz programmable
- Transmission distance: 8 meters (open area)
- Logic Interface Type: UART TTL serial port
- Communication format: 8N1
- AT command mode baud rate: 9600bps(Fixed value)
- Transparent transmission mode baud rate: 115200 (default for Arduino UNO R3), can be modified to other values by command
- Operating mode: For the USB transmitter module, break apart the USB case, to press and hold the button, then it will enter the AT command mode, release the button to enter the transparent mode. For receiver module, when CMD pin is low, it is AT command mode and it can be used to set the parameters of the module; When CMD is high or float, it is transparent mode, at this mode, when it receive data from transmitter, it will be pulled down for 9ms to reset Arduino.
- Antenna: Built-in PCB antenna
- Great for Arduino Programmer, DIY, smart car program burner, wireless sensor
