Raspberry Pi Pico WH

The Raspberry Pi Pico W is an exceptional microcontroller board that offers excellent value for money by incorporating WiFi capabilities. This board is an enhancement of the Raspberry Pi Pico, featuring an Infineon CYW43439 wireless chip. This chip supports IEEE 802.11 b/g/n wireless LAN, Bluetooth® 5.2, Bluetooth® Classic, and Bluetooth® Low Energy (BLE) functionality. It also allows for the configuration of Bluetooth® Classic and BLE, either individually or simultaneously.

The Raspberry Pi Pico W is a high-performance, low-cost microcontroller board with flexible digital interfaces. It features the RP2040, Raspberry Pi's first in-house designed microcontroller. The board is designed with minimal external circuitry to support the RP2040 chip. Most of the RP2040 microcontroller pins are available to the user on the left and right edges of the board. Four RP2040 IO are used for internal functions.

The Raspberry Pi Pico W uses an on-board buck-boost SMPS that generates the required 3.3 volts from a wide range of input voltages (~1.8 to 5.5V). This flexibility allows the unit to be powered from various sources, such as a single Lithium-Ion cell or three AA cells in series. The Pico's flash memory can be reprogrammed using USB or via the Serial Wire Debug (SWD) port, which can also be used to interactively debug code running on the RP2040.

The Raspberry Pi Pico W is designed to use either soldered 2.54mm pin-headers or can be used as a surface mountable "module". The user IO pins are also castellated, and there are SMT pads underneath the USB connector and BOOTSEL button, which allow these signals to be accessed if used as a reflow-soldered SMT module.

NOTE: This variation comes with a set of male headers pre-soldered to all through-hole vias (thus the Pico WH instead of just the Pico W). The spacing remains 2.54mm and breadboard compatible.
