Description: SPP-C Bluetooth module is designed for intelligent wireless data transmission to build, follow the V2.1 + EDR Bluetooth specification. This module supports UART interface and supports SPP Bluetooth serial port protocol. It has the advantages of low cost, small size, low power consumption and high sensitivity of receiving and sending. It can realize its powerful function with only a few external components. Features: Bluetooth V2.1 + EDR Bluetooth Class 2 Built-in PCB RF antenna Supports UART interface 3.3V power supply LAYOUT Note: 1, SPP-C Bluetooth module serial port level to be 3.3V, if the 5V level system and the need to increase the level conversion chip. 2, the Bluetooth signal is greatly affected by the surrounding, such as trees, metal, wall and other obstacles will have a certain Bluetooth signal absorption or Shielding, it is recommended not to be installed in the metal casing. 3, because the metal will weaken the antenna function, it is recommended to the module Lay board, the module antenna do not shop below and alignment, the best to hollow out.
