The Raspberry Pico W and Pico WH (with Headers) is a microcontroller based developement board. At this heart is a RP2040 microcontroller chip designed by Raspberry Pi in UK. It features a Dual Core ARM Cortex-M0+ processor running upto 133 MHz with 264 KB of on-chip SRAM. The Pico also has a 2 MB of onboard Flash memory, providing enough space for code and data storage.
The "W" in the Pico W standards for wireless connectivity. Pico W offers offers 2.4GHz 802.11 b/g/n wireless LAN support and Bluetooth 5.2, with an on-board antenna, and modular compliance certification. It can be operated in both station and access point modes.
Pico has extensive I/O capabilities with 26 GPIO Pins, including 3 Analog Inputs and lots of interfacing options including 2 × SPI, 2 × I2C, 2 × UART, 3 × 12-bit ADC, 16 × controllable PWM channels. Moreover, 26 of the GPIO pins are multi-function, which means we can configure those pins to a different behavior like UART/I2C/SPI/GPIO.
It includes a USB 1.1 with device and host support, allowing easy connection to PCs or other USB devices, this enables drag-and-drop programming feature that simplifies the process of loading and updating code on the device using mass storage over USB.
- Castellated module allows soldering direct to carrier boards (Raspberry Pi Pico and Pico W only)
- Drag-and-drop programming using mass storage over USB
- Low-power sleep and dormant modes
- Accurate on-chip clock
- Temperature sensor
- Accelerated integer and floating-point libraries on-chip
