The Raspberry Pi Pico is a compact, low-cost microcontroller board that has gained popularity for its versatility and ease of use in a variety of applications. Here's a detailed overview of its features:
The Pico is powered by the RP2040 microcontroller chip, which was designed by Raspberry Pi in the UK. This chip boasts a dual-core Arm Cortex M0+ processor that can flexibly run up to 133 MHz, making it suitable for a range of tasks from simple to complex。
It comes with 264KB of SRAM and 2MB of on-board flash memory for storing code and data. The Pico also supports up to an additional 16MB of external flash memory via a dedicated QSPI bus, which is beneficial for applications that require more storage。
One of the standout features of the Pico is its USB 1.1 support, which allows it to act as both a device and a host. This opens up possibilities for connectivity with a wide range of peripherals and devices.
The Pico is designed with low-power sleep and dormant modes, which can extend battery life in applications where power conservation is essential.
Programming the Pico is simplified through drag-and-drop programming using mass storage over USB. This means you can load your code onto the Pico by simply dragging a file onto its drive, much like transferring files to a USB stick.
The board is equipped with 26 multi-function GPIO pins, which can be configured for various functions such as input/output, PWM, ADC, and more. This flexibility allows the Pico to interface with a wide array of sensors and components.
For communication, the Pico offers a range of interfaces including 2 UARTs, 2 SPI controllers, and 2 I2C controllers. These interfaces enable the Pico to communicate with other devices and modules.
