Arduino Nano V3 (clone)

Prototype #2

  • Selfie of new working prototype based on Arduino Nano 3.0 (Clone) and its parts (+new power module) and box that will hide this little mess. :-)

Prototype #2.1

  • Rewired TX/RX to D3 and D4 pins from hardware TX/RX pins. There was communication conflict with integrated USB-to-serial chip. Software serial is now used to communicate with Bluetooth module. It just works.
  • Finally working Android App with basic features - More information and download link at Software Page

Part list:

  • Nano V3.0 ATMEGA328P Development Board for Arduino - Clone of Arduino Nano V3
  • JY-MCU Bluetooth Wireless Serial Port Module for Arduino - Bluetooth Module
  • DIY 5V Boost PCB Module for Mobile Power - Charges battery while connected to USB and powers module while not connected to USB.
  • Li-Ion battery - the one on picture is from some kind of 3G modem, battery from any old cellphone should be fine. So recycle one.
  • micro USB male connector - Buy new one in you local electronics store or somewhere else. You usualy cannot recycle any old data/charging cable, since they dont have all 5 pins connected.
  • Some nice box - like the one on the picture - from ADSL splitter.
  • Some wires - You can recycle old USB cable. I recommend to use just power pair from it, since data pair is thinner.
