Raspberry Pi Pico BLE expansion board(21474)

Raspberry Pi Pico BLE Expansion Board(21474 ) - allows you to connect Raspberry Pi Pico to Bluetooth-enabled devices. This module supports two modes of operation: SPP (Serial Port Profile) and BLE (Bluetooth Low Energy), which is an energy-efficient Bluetooth technology used to transfer small amounts of data over long distances. SPP allows data to be transmitted over the Bluetooth serial port, which allows you to connect your Raspberry Pi Pico to other Bluetooth devices as a data exchange node.

Bluetooth 5.1 is a version of the Bluetooth standard that includes a variety of improvements and new features over previous versions. It offers faster data rates, longer communication ranges, improved connection stability, and support for new protocols and features.

Using the Dual-Mode Bluetooth Module for Raspberry Pi Pico allows you to extend the wireless communication and interaction capabilities of Raspberry Pi Pico with other Bluetooth devices. For example, you can use it to connect with Bluetooth devices such as smartphones, headphones, keyboards, or other Bluetooth-enabled microcontrollers for data transfer or control.

Key features:

• Standard Raspberry Pi Pico connector supports the Raspberry Pi Pico series
