RX jump to MRX, TX jump to MTX, and remove the atmega328P from arduino. By doing this, we can directly monitor serial port output using the USB port. The default baud rate is 115200. 2. Install X-CTU serial terminal console: http://www.cutedigi.com/pub/software/setup_xctu_5100.exe Second Tutorial: Now we are going to use atmega328P's UART to talk to USB, and soft serial of atmega328P to talk to ATWIN. Before we do that, we have to change ATWIN's data rate to 9600 as soft serial can't go to 119200. In first tutorial setup, do: AT+IPR=9600 to set the baud rate to 9600. Now set the jumper RX to D3, and TX to D2. SO that atmega328P's UART to talk to USB and soft serial of atmega328P to talk to ATWIN: Download: Product Wiki Payment ·         We only accept Paypal at this moment ·         If  you want to buy a large quantity please contact me directly Shipping: Items will be shipped within 2 business days after payment is completed (Saturday, Sunday and public holidays is not counted) United Status/Canada/United kingdom/ Australia/ Usually 5 – 20 Business Days Italy/France/Spain/Germany/ Europe Country Usually 10 – 40 Business Days Singapore/Korea/Thailand etc..Asia  Country Usually  5-20 Business Days Brazil Usually 30-60 Business Days Note:  This Item ship by International Registered Mail (with Tracking number)
