This is a , fast, and versatile board built using RP2040, the microcontroller chip. Programmable in C and for MicroPython, Pico W is to a range of applications and skill levels, and started is as easy as dragging and dropping a file. More experienced users can take advantage of for Pico's peripheral set, including SPI, I2C, and eight Programmable I/O (PIO) state machines for custom peripheral support. Connect Wirelessly: Network your Pico for a complete IoT solution. for Pico W comes with a fully certified module on board featuring 2.4GHz 802.11n wireless LAN, making it the perfect solution for loT applications and projects requiring wireless communication.
