Various options for easily powering the unit from micro USB, external supplies or batteries.Simple yet highly flexible power supply architecture.
23 GPIO are digital-only, with three also being ADC capable.Exposes 26 multi-function 3.3 V general purpose I/O (GPIO).40 pin 21 x 51 mm 'DIP' style 1 mm thick PCB with 0.1" through-hole pins also with edge castellations.Micro USB B port for power and data (and for reprogramming the flash).On-board single-band 2.4 GHz wireless interfaces (802.11n).RP2040 microcontroller with 2 MB of flash memory.The wireless interface is connected via SPI to the RP2040. Raspberry Pi Pico W has been designed to be a low cost yet flexible development platform for RP2040 with a 2.4 GHz wireless interface using an Infineon CYW43439. In addition, there is 2 MB of on-board QSPI flash memory for code and data storage. The RP2040 microcontroller chip ("Raspberry Silicon") offers a dual-core ARM Cortex-M0+ processor (133 MHz), 256 KB RAM, 30 GPIO pins, and many other interface options. Raspberry Pi Pico W is a microcontroller board based on the Raspberry Pi RP2040 microcontroller chip.
