Raspberry Pi Pico WH

Raspberry Pi Pico WH has been designed to be a low cost yet flexible development platform for RP2040, with a 2.4GHz
wireless interface and the following key 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
