Overview

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

Basic 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

Hardware

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). To change the mode, you need to reset the iteaduino BT after you put the switch.

Communicate mode set jumper

There is a jumper to set the connections of HC-05. When the jumpers are set in B side, the HC-05 communicates with FT232R to USB/PC, when the jumpers are set to A, the HC-05 communicates with Atmega328P(onboard).
