BlueSMiRF v2 Wireless Serial Link, up to 921600bps, ESP32-PICO-MINI-02 Module with Built-in PCB Antenna, Input Voltage: 3.3V to 5V, Board Dimensions: 44.2mm x 15.22mm

The SparkFun BlueSMiRF v2 is a wireless serial link. These boards work as a wireless serial UART pipe and are a great wireless replacement for serial cables. Simply pair, connect, and transmit serial data between your TX/RX lines! Any serial stream from 2400 to 921600 baud can be passed seamlessly between two devices. Duplex transmissions up to 921600bps are supported. What does this mean? You can throw a book at each BlueSMiRF, which will correctly buffer, transmit, and deliver the data streams, byte perfect, to both radios.

BlueSMiRF v2 has a multitude of exciting improvements over the original. The BlueSMiRF pinout is the same as previous Mates and USB-to-serial converters (i. e., FTDI, CH340, etc. ), making it extremely easy to hook up to many common Arduino development boards and high-precision GNSS breakout boards. The board can be connected directly with an Arduino Pro, Pro Mini, LilyPad Arduino 328 Main, ZED-F9P, ZED-F9R, UM980, SerLCD, or any board with a standard 6-pin serial connector. We broke out the pins to the 1x6 header for this version of the board.

You'll need to either solder a 1x6 female header or striped wires to the PTHs before being able to connect to another device. The SparkFun BlueSMiRF v2 is perfect for short-range applications up to 100ft (33m) indoors that require easy to setup, point-to-point communication. A BlueSMiRF can be connected to a phone or computer to view data or remote control easily. Two BlueSMiRFs can also be easily connected using t
