Vi Điều Khiển Raspberry Pi RP2040 Rev B2 Microcontroller được chính Raspberry Pi thiết kế dựa trên kiến trúc dual-core ARM Cortex-M0+ với xung nhịp tối đa lên đến 133Mhz, RP2040 còn có 264KB RAM nội và hỗ trợ bộ nhớ Flash ngoài lên đến 16MB cũng như đầy đủ các giao tiếp cơ bản UART, I2C, SPI,....
Microcontrollers connect the world of software to the world of hardware. They allow developers to write software which interacts with the physical world in the same deterministic, cycle-accurate manner as digital logic. They occupy the bottom left corner of the price/performance space, outselling their more powerful brethren by a factor of ten to one. They are the workhorses that power the digital transformation of our world.
RP2040 is the debut microcontroller from Raspberry Pi. It brings our signature values of high performance, low cost, and ease of use to the microcontroller space.
With a large on-chip memory, symmetric dual-core processor complex, deterministic bus fabric, and rich peripheral set augmented with our unique Programmable I/O (PIO) subsystem, it provides professional users with unrivalled power and flexibility. With detailed documentation, a polished MicroPython port, and a UF2 bootloader in ROM, it has the lowest possible barrier to entry for beginner and hobbyist users.
RP2040 is a stateless device, with support for cached execute-in-place from external QSPI memory. This design decision allows you to choose the appropriate density of non-volatile storage for your application, and to benefit from the low pricing of commodity Flash parts.
RP2040 is manufactured on a modern 40nm process node, delivering high performance, low dynamic power consumption, and low leakage, with a variety of low-power modes to support extended-duration operation on battery power.
