This time Raspberry Pi Foundation developed a powerful device Raspberry Pi Pico that is powered by micro-controller RP2040. It is a compact microcontroller board that would make the work easier for the users which will raise the quality of the products.
Some users want to purchase Raspberry Pi Pico for their projects but they would also need a GPIO Expansion pin so that they do not have to solder the circuits with the Raspberry Pi Pico. So this GPIO expansion board is perfectly designed for Raspberry Pi Pico. No need to field solder, all pin lead out, support a variety of data protocols, including I2C,UART, analog, digital.
Jargon buster
Plain-language definitions for the technical terms used above.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- RP2040
- A microcontroller chip used on many maker boards, with enough speed and flexible I/O for some camera and display projects. Compatibility with RP2040 matters because camera modules often need many pins and careful timing to read image data successfully.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
