Overview

IteaduinoBT3.jpg

Iteaduino-BT is an Arduino compatible board with a master/slave Bluetooth Module HC-05. It based on Arduino UNO/Duemilanove, 100% compatible with its existing program and shields, but with the bluetooth wireless funcion. The power consumption is about 50% of the original Arduino boards.

Features

  • Design for Bluetooth communication
  • Compatible with Arduino UNO/Duemilanove pins, holes and dimensions
  • Wide range external input from 7~23V DC
  • Pins out for Sensor and Servo
  • 3.3V/5V Operating Voltage selection

Digital/Servo Interface: D0~D13 pin

Sensor Interface: A0 A1 A2 A3 A4 A5 pin

HC-05 operate mode set switch

There is a 1P2T switch for HC-05 operation mode set. When the switch is set on “DAT” side, the HC-05 will work in the data mode. When the switch is set on “CMD” side, the HC-05 will work in command mode, in this mode, Iteaduino/FT232R could send the AT command to centigrade the HC-05 module (Using Baud Rate 38400).

Communicate mode set jumper

There is a jumper to set the connections of HC-05. When the jumper is set in A, the HC-05 communicates to FT232R, when the jumper is set to B, the HC-05 communicates to Atmega328P(board).
