Raspberry Pi Pico W adds 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)
• WPA3
• Soft access point supporting up to four clients

Features:

• RP2040 microcontroller with 2MB of flash memory
• On-board single-band 2.4GHz wireless interfaces (802.11n)
• Micro USB B port for power and data (and for reprogramming the flash)
• 40 pin 21mmx51mm ‘DIP’ style 1mm thick PCB with 0.1″ through-hole pins also with edge castellations
• Exposes 26 multi-function 3.3V general purpose I/O (GPIO)
• 23 GPIO are digital-only, with three also being ADC capable
• Can be surface mounted as a module
• 3-pin ARM serial wire debug (SWD) port
• Simple yet highly flexible power supply architecture
• Various options for easily powering the unit from micro USB, external supplies, or batteries
• High quality, low cost, high availability
• Comprehensive SDK, software examples, and documentation
• Dual-core Cortex M0+ at up to 133MHz
• On-chip PLL allows variable core frequency
• 264kByte multi-bank high-performance SRAM
