The Raspberry Pi Pico W is based on the Raspberry Pi RP2040 chip, but with wireless connectivity added! The Pico W boast an Infineon CYW43439 wireless chip which supports IEEE 802.11 b/g/n wireless LAN, and Bluetooth 5.2. Do note that only wireless LAN is supported right now.
At the heart of the Pico W you find the RP2040, a Raspberry Pi-designed chip, which features two ARM Cortex-M0+ cores clocked at 133MHz, 256KB RAM, 30 GPIO pins, and a broad range of interfacing options. This is paired with 2MB of on-board QSPI Flash memory for code and data storage.
