Raspberry Pi Pico 2 is the anticipated successor to the Raspberry Pi Pico, continuing Raspberry Pi’s commitment to providing affordable, high-performance microcontroller boards for a wide range of applications. While the Raspberry Pi Pico 2 has not been officially announced at the time of this writing, we can infer potential features and improvements based on trends in the microcontroller market and Raspberry Pi’s previous developments. Here’s what we might expect:
- Dimensions: Likely to retain a similar form factor to the original Pico, ensuring compatibility with existing Pico accessories and enclosures.
- Processor:
- An upgraded version of the RP2040 or a new chip, potentially with a more powerful Arm Cortex-M core, like Cortex-M4 or Cortex-M7, for enhanced performance.
- Memory:
- Increased SRAM, possibly to 512KB or more, to support larger and more complex applications.
- Integrated flash memory on board, reducing the need for external flash storage, perhaps up to 16MB or even more.
- Programmable I/O (PIO):
- An evolution of the Programmable I/O system, with more PIO state machines or improved efficiency for even more flexible I/O operations.
- I/O Interfaces:
- GPIO: Possibly more GPIO pins or enhanced capabilities, with continued support for UART, SPI, I2C, PWM, and more.
- USB: Likely to retain or upgrade the USB controller to USB 2.0 for faster data transfer rates, maintaining both device and host capabilities.
- ADC: Improved resolution or additional ADC channels for more precise analog input.
- SPI: Enhanced SPI performance or additional controllers.
- I2C: Increased data rates or additional I2C controllers.
- UART: More UART peripherals or higher baud rates.
- PWM: More PWM channels or better resolution for control applications.
- Development Ecosystem:
- Continuation and expansion of the current development ecosystem, with updated SDKs, libraries, and examples tailored for the new hardware.
- Continued support for MicroPython, CircuitPython, and C/C++, with potential improvements or new language support.
- Enhanced drag-and-drop programming interface, making it even easier to load code onto the board.
- Power:
- Similar wide operating voltage range with potential improvements in power efficiency.
- Low power modes and sleep capabilities for battery-powered applications might be further refined.
- Price:
- While still aiming to be affordable, the Pico 2 might be slightly more expensive due to enhanced features and capabilities.
