Raspberry Pi Pico W [DEV-20173] - (AD86652)

Description:

The Raspberry Pi Pico W builds on the excellent cost-performance metrics of the Pico and adds WiFi to the board. The Pico W features the same attributes as the Raspberry Pi Pico and also incorporates an Infineon CYW43439 wireless chip. CYW43439 supports IEEE 802.11 b/g/n wireless LAN and Bluetooth® 5.2, enabling Bluetooth® Classic and Bluetooth® Low Energy (BLE) functionality, with the temporary exception of ACL/SCO, along with BLE Central and Peripheral features. Things are also configurable so you can enable Bluetooth® Classic and BLE individually or have both available at the same time.

The Raspberry Pi Pico line is a high-performance, low-cost microcontroller board with flexible digital interfaces. It features the RP2040, marking Raspberry Pi's first internally designed microcontroller. Pico provides minimal (but flexible) external circuitry to support the RP2040 chip (Flash, crystal, power supplies, and decoupling and USB connector). Most of the RP2040 microcontroller pins are brought out to user I/O pins on the left and right edges of the board. Four RP2040 I/Os are used for internal functions: controlling an LED, power control of the integrated switched-mode power supply (SMPS), and sensing system voltages.

Pico uses an integrated buck-boost SMPS that can generate the necessary 3.3 volts (to power the RP2040 and external circuitry) from a wide range of input voltages (~1.8 to 5.5V). This allows significant flexibility for powering the unit from various sources, such as a single lithium-ion cell or three AA cells in series. Battery chargers can also be very easily integrated with the Pico power chain. Reprogramming Pico's flash memory can be done via USB (simply drag and drop a file onto Pico, which appears as a mass storage device) or via the Serial Wire Debug (SWD) port. The SWD port can also be used to interactively debug code running on the RP2040.

Pico has been designed to use 0.1" soldered pin headers (it has a wider 0.1" pitch than a standard 40-pin DIP package) or can be used as a surface-mount "module" since the user I/O pins are also castellated. There are SMT pads under the USB connector and BOOTSEL button, which allow access to these signals if used as a reflow soldered SMT module.
