Raspberry Pi microcontroler - RP2040 - SC0914

TheRP2040 is the debut microcontroller of the Raspberry Pi Foundation. It was first used in the Raspberry Pi Pico module and in modules from other manufacturers, including Arduino, which unveiled its Arduino Nano RP2040 Connect module. It is a high-performance, dual-core chip based on ARM Cortex M0+ clocked at 133 MHz. It has a large amount of built-in SRAM, unique programmable I/O (PIO) and other popular communication interfaces. Detailed documentation, a fine-tuned MicroPython port and the UF2 bootloader located in ROM allow even novice users and hobbyists to get started with the microcontroller. The RP2040 has been developed on the state-of-the-art 40nm technology process, providing high performance, low power consumption, with multiple low-power modes that allow the chip to run on battery power for long periods of time. The microcontroller is housed in a QFN-56 enclosure.

The Raspberry Pi RP2040 microcontroller has 30 GPIO pins with popular communication interfaces such as:

• 2 x UART
• 2 x SPI
• 2 x I2C
• 16 x PWM
• USB 1.1 and PHY controller
• 8 PIO
• 4 x analog inputs

With these interfaces, the RP2040 microcontroller can be used widely - from projects using machine learning to those that will control motors. The I/O interfaces operate at 3.3V.
