Post Arduino compatible Nano with CH340 USB IC (HCARDU0094)


The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328. It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one. The version of the nano differs in that it doesn't use the standard FTDI chip to control the USB interface. Instead it uses the CH340. All this means for you is that you need to download drivers (supplied below). Once the drivers are installed, the nano will work in exactly the same way as those that use the FTDI chip, it's just cheaper to manufacture, and thus we're able to offer them at an excellent price.

Underside of the Nano


Microcontroller: ATmega328
Operating Voltage (logic level): 5 V
Input Voltage (recommended): 7-12 V
Input Voltage (limits): 6-20 V
Digital I/O Pins: 14 (of which 6 provide PWM output)
Analogue Input Pins: 8
DC Current per I/O Pin: 40 mA
Flash Memory: 32 KB of which 2 KB used by bootloader
Clock Speed: 16 MHz
Dimensions: 0.73" x 1.70"

Windows Installation Instructions

Drivers are available in the link below. Simply download and unzip them, plug in your nano and when the new hardware is detected, point the wizard to the folder you just unzipped to and it should install without any problems.

Windows Driver can be downloaded here

MAC installation instructions

New code signed version confirmed to work with 10.12 Sierra


Older code signed version confirmed to work with El Capitan



Download the driver (you must be logged in to download).

Once downloaded, double-click the zip file to unzip it.

Run installer found in that folder.

If asked to restart, do not restart just yet.

Now restart your Mac.

Unfortunately, the above drivers don't work in 'El Capitan' - however there is a workaround... Go to:- ... itan-os-x/

Follow the instructions. Once you've booted back into your normal account, if you run csrutil status, you should get a terminal output like this:-
csrutil status
System Integrity Protection status: enabled (Custom Configuration).

   Apple Internal: disabled
   Kext Signing: disabled
   Filesystem Protections: enabled
   Debugging Restrictions: enabled
   DTrace Restrictions: enabled
   NVRAM Protections: enabled

This is an unsupported configuration, likely to break in the future and leave your machine in an unknown state.

You will now find that your Uno+ will show up (USB-wise) in the Arduino IDE

Hope this helps!
