Bluetooth Modem - BlueSMiRF Silver

本商品為研發實驗用的模組，無法隨插即用，須經專業背景人士（如：工程師、研究生、師生）撰寫程式、燒錄、接線等二次加工後，才具備訊號傳輸功能。
並非直接插電後可直接使用之射頻模組，非屬電信管制射頻器材，購買前請詳閱商品說明。  

Description:
 The BlueSMiRF Silver is the latest Bluetooth wireless serial cable replacement from SparkFun Electronics! This version of the popular BlueSMiRF uses the RN-42 module which has a bit less range than the RN-41 module used in the BlueSMiRF Gold. These modems work as a serial (RX/TX) pipe. Any serial stream from 2400 to 115200bps can be passed seamlessly from your computer to your target.
The remote unit can be powered from 3.3V up to 6V for easy battery attachment. All signal pins on the remote unit are 3V-6V tolerant. No level shifting is required. Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit if you need to attach this to a computer.
Unit comes without a connector. Please see related male and female pins below.
