Replace a wired UART connection with a Bluetooth serial link using BlueSMiRF v2. It connects through TX and RX and supports full-duplex data transfer across a configurable baud-rate range. The familiar pinout matches earlier Bluetooth Mates and standard USB-to-serial breakout layouts, helping integrate the module into serial communication prototypes.
Before you buy
