Raspberry Pi Pico WH is just like the classic Pico but adds pre-soldered headers, a new 3-pin debug connector, and an on-board single-band 2.4GHz wireless interfaces (802.11n) using the Infineon CYW4343 while retaining the Pico form factor. The on-board 2.4GHz wireless interface has the following features:
Wireless (802.11n), Single-band (2.4 GHz) WiFi with WPA3 and Soft Access Point supporting up to 4 clients
Bluetooth Low Energy - note this isn't supported in software yet, its just a hardware capability.
The wireless interface is connected via SPI to the RP2040 microcontroller and has a micropython driver for wireless capability
Due to pin limitations (the Pico brings out all the GPIO) some of the wireless interface pins are shared with the exposed pads:
The SPI CLK is shared with VSYS monitor, so only when there isn’t an SPI transaction in progress can VSYS be read via the ADC.
The Infineon CYW43439 SPI DIN/DOUT and IRQ all share one pin on the RP2040. Only when an SPI transaction isn’t in progress is it suitable to check for IRQs.
The interface typically runs at 33MHz.
RP2040 Chip features:
Dual ARM Cortex-M0+ @ 133MHz
264kB on-chip SRAM in six independent banks
Support for up to 16MB of off-chip Flash memory via dedicated QSPI bus
DMA controller
