EMS Blue Shield is an add-on module/Shield for DT-Inoduino AVR module or module/Arduino Arduino Compatible. This module serves as a Bluetooth module for Arduino microcontroller module. By using this module the module Ardunio can easily connect to a bluetooth network by simply using UART TTL interface.

The Bluetooth module used on the shield is a series BTM230 that are included in class 1 bluetooth modules. Bluetooth class 1 module has a power output of approximately 100mW (17dBm typical). EMS Blue Shield is a bluetooth module fitted with SPP (Serial Port Profile) bluetooth module, so it can only be used to send data to serial (not transfer files or audio on mobile/PC in General).

EMS Bluetooth Shield has a pin connection layout compatible with Arduino module so that the module can be used on various types of Arduino or Arduino Compatible, such as: DT-AVR Inoduino, DT-Leoduino AVR, AVR-Unoduino DT, DT-AVR Maxiduino, Arduino UNO, Arduino Mega, Ardunio Leonardo.

Dimensions: 5.45 cm (P) x 5.4 cm (L) x 2 cm (T)
