Raspberry Pi Pico is known for its affordability, with a price tag that makes it accessible to hobbyists and students. On the other hand, Xiao NRF52840 Sense is slightly more expensive, but it offers additional features that may justify the higher cost for some users.
Performance
When it comes to performance, Raspberry Pi Pico and Xiao NRF52840 Sense have different capabilities. Raspberry Pi Pico is powered by a dual-core ARM Cortex-M0+ processor running at 133MHz, while Xiao NRF52840 Sense features a more powerful ARM Cortex-M4 processor running at 64MHz. This difference in processing power can impact the performance of the boards in tasks that require more computational resources.
Connectivity
Connectivity is another important aspect to consider when comparing Raspberry Pi Pico and Xiao NRF52840 Sense. Raspberry Pi Pico comes with built-in support for USB connectivity, making it easy to connect to a computer for programming and debugging. On the other hand, Xiao NRF52840 Sense offers Bluetooth and Wi-Fi connectivity, allowing for wireless communication with other devices.
Memory
Memory capacity is a crucial factor in determining the capabilities of a microcontroller board. Raspberry Pi Pico comes with 264KB of RAM and 2MB of flash memory, providing enough storage for most projects. In comparison, Xiao NRF52840 Sense offers 256KB of RAM and 1MB of flash memory, which may limit the size and complexity of projects that can be developed on the board.
GPIO Pins
GPIO (General Purpose Input/Output) pins are essential for connecting external components to a microcontroller board. Raspberry Pi Pico offers 26 GPIO pins, providing ample flexibility for connecting sensors, actuators, and other peripherals. Xiao NRF52840 Sense, on the other hand, comes with 21 GPIO pins, which may be sufficient for many projects but could be limiting for more complex applications.
