Product description: BlueSMiRF v2 - Bluetooth wireless communication module - ESP32-PICO-MINI-02 - with connectors - SparkFun WRL-23287
SparkFun BlueSMiRF v2 is a development board equipped with ESP32-PICO-MINI-02 . It supports wireless Bluetooth communication , any serial stream from 2400 bps to 921600 bps can be seamlessly transmitted between two devices. BlueSMiRF v2 also supports duplex transmissions up to 921600 bps, allowing for excellent buffering, transmission and delivery of the data stream while maintaining full byte compatibility. The module has pre-assembled pins, making it simple and fast to use - it can be directly connected to boards such as Arduino Pro, Pro Mini, LilyPad Arduino 328 Main, ZED-F9P , ZED-F9R, UM980, SerLCD or any board with a standard 6-pin serial connector. It is ideal for short-range applications up to 33 m indoors that require easy setup of point-to-point communication, making it useful for prototyping and testing IoT applications based on wireless data transmission.
