WiFi DipCortex – ARM Cortex Development Board

WiFi DipCortex is a simple but powerful WiFi connected development board enabling you to create connected devices quickly and easily. It uses a NXP ARM Cortex M3 LPC1347 and a TI SimpleLink CC3000MOD in a tiny 40pin DIP package.

The WiFi DipCortex is the heart of your next WiFi connected product enabling you to create connected sensors, intelligent controls, smart displays or anything you can imagine.

The CC3000 WiFi module driver has been ported to the WiFi DipCortex’s NXP processor and an example that exercises the module will be found on our GitHub page (Very soon). This example will show you how to :

  • Connect to a network manually
  • Trigger smart connect to pass the connection details via smartphone
  • Use DHCP to retrieve an IP, Gateway, DNS and Subnet mask
  • Specify a static IP address
  • Listen and send UDP/TCP packets
  • Retrieve the date from an NTP server
  • HTTP put data to web server, such as Xively
  • HTTP get data from a web server
  • USB CDC ( Virtual Com Port ) to manually control via putty/serial terminal

Updating the WiFi DipCortex’s code is easy and can be done by holding the boot button while plugging in USB, it appears as a removable drive and you simply drag and drop your new firmware on to it.

The CC3000 module has its own built-in firmware, we have updated this to version 1.19, the latest service pack from TI. This requires host firmware driver version 13, which we use in our GitHub example.

Power Consumption

For battery backed operations it would make sense to power up the CC3000 module send or check for data and then power it off. The module can connect in around a second to a previously used access point. Using a static IP it is then ready to go, a dynamic IP can take a few more seconds more to obtain.

  • Sleep, less than 1mA at 5V
  • Wifi Active, Average 120mA at 5V


CC3000 comes Pre-Certified by TI for FCC, ETSI, IC and CE. TI detail reuse of their certification here

Guides – Software Development

The WiFi DipCortex has a standard 10way debug header with the SWD pins connected. A variety of IDE’s and compilers can be used to create code for the DipCortex, IAR, Keil, CodeRed, LPCXpresso and GCC.

LPCXpresso is a free option specifically for the NXP Lpc range.

How to use the LPC Pins as GPIO – General Purpose IO

Getting started with mbed on the Wifi DipCortex – Various examples including USB CDC, HTTP, TCP, UDP, Websocket and more.
