2  Development / Other Hardware Development / Bluno-World First BLE(bluetooth 4.0) with Arduino UNO on: November 16, 2013, 10:55:07 am
It's time to get Bluetooth 4.0 into your project, together with your phone! For aficionados of smart devices and wearables, now you can go further than hacking things bought in the market to building your own prototype out of garage. The Bluno board is first of its kind in intergrating BT 4.0(BLE) module into Arduino Uno, making it an ideal prototyping platform for both software and hardware developers to go wireless. You will be able to develope your own smart bracelet , smart pedometer and more. Through the low- power Bluetooth 4.0 technology, real-time low energy communication can be made really easy.

6  Development / Other Hardware Development / Re: which is best Wifi shield for arduino? on: March 16, 2013, 11:38:47 am
Try this

It uses a mature WizFi210 chip. It provides the bridging from TTL serial port communication to IEEE802.11b/g/n wireless communication. So any device with TTL serial ports can easily be connected with this WIFI module and controlled and managed remotely through a wireless network. Different kinds of communication protocols and encryption algorithms are integrated with the module. The Arduino architecture enables you to easily integrate this module into any Arduino based project.

It is  not the first small Leonardo - my Leonardino (little leonardo) was out quite a while ago - and I brought out 25 IO lines,

All right. You are the first guy smiley-twist smiley-twist.   Your work looks nice too.

DFRobot just released the first Nano sized Leonardo- Dreamer Nano

The Dreamer Nano V4.0 is a surface mount breadboard embedded version of the ATMEGA 32U4 with integrated Micro USB. It has everything that Leonardo has (electrically).Physically, it is just missing power jack to save space.
Using the ATmega32U4 as its sole microcontroller allows it to be cheaper and simpler. Also, because the 32U4 is handling the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the USB-HID protocol!
The Dreamer Nano v4.0 is compatible with most Nano shield in the market. It's suitable for projects that require a compact size controller system.

  • Input Voltage: 6.5-12v (VIN) / 5v (Micro USB)
  • ATmega32u4 Microcontroller
  • 20 Digital I/O Pins
  • 7 PWM Channels
  • 12 ADCs
  • 16MHz Clock Speed
  • 32 KB Flash Memory
  • Compatible with most of Nano shield
  • Size: 45x20x20mm
