Review on 5Pcs Longruner Arduino Mini Nano V3.0 ATmega328P Micro Controller Board Module With USB Cable For ArduinoIDE by Chris Morales

They should add some instructions for setting up the IDE. I downloaded the Arduino IDE 1.8.7. Then to configure the IDE:Tools.Board.Arduino NanoTools.Processor.AtMega328P(Old Bootloader)Tools.Port ComXX -> See comments below if it doesn't show the port you that you expect.Compile your sketch. Press the reset button in the middle of the board then quickly hit the upload button on the IDE.Serial ports. Windows 7 automatically downloaded the CH340 drivers. The board doesn't have the usually found FTDI serial port chipset. Look in device manager to see if you have its serial port. Mine showed up as "USB-SERIAL CH340 (COM20). So under ports on the Arduino IDE I chose Tools.Port.COM20.
