Raspberry Pi Pico WH

Description

• Following the hugely popular Raspberry Pi Pico, the new Raspberry Pi Pico W is a wireless-enabled version of the RP2040-based board, adding 2.4GHz 802.11n WiFi connectivity!
• The addition of wireless connectivity opens up the Pico W to a vast new range of projects such as remote sensor readings, remote control, home automation, mini web servers, wireless GPIO pin control and much, much more!
• At the heart of the Pico W is the RP2040 – the same chip used in the original Raspberry Pi Pico, featuring two ARM Cortex-M0+ cores clocked at 133MHz; 256KB RAM; 30 GPIO pins; and a broad range of interfacing options. This is paired with 2MB of onboard QSPI Flash memory for code and data storage.
• WiFi is enabled via the use of an Infineon CYW43439 wireless chip. The CYW43439 supports IEEE 802.11 b/g/n wireless LAN, and Bluetooth 5.2; however only wireless LAN is software-supported at launch.

With the same footprint and same RP2040 chip, this WiFi Pico can be used as a drop-in replacement for your existing Raspberry Pi Pico projects, upgrading them with WiFi. Just grab a Micro-USB cable (or our handy Pico Essential Kit with a USB cable, headers and more!), install the latest MicroPython Pico W specific U2F file and start programming!

The Pico W can be quickly and easily programmed using MicroPython and C/C++* using popular editors such as Thonny. Learning how to use the Pico and MicroPython is also very easy thanks to the dedicated Getting Started projects and guide. There’s also a guide for connecting to the internet with the Raspberry Pi Pico W.

The main chip on board is the RP2040 made by Raspberry Pi (their first in-house microcontroller chip!) and is a dual-core ARM Cortex M0+ processor, with a flexible clock running up to 133MHz. WiFi is enabled via the use of an Infineon CYW43439.

Dual-Core Arm Cortex M0+ Processor, Flexible Clock Running Up To 133 MHz

A few RP2040 GPIO pins are used for internal board functions:

• GPIO29 OP/IP wireless SPI CLK/ADC mode (ADC3) to measure VSYS/3
• GPIO25 OP wireless SPI CS – when high also enables GPIO29 ADC pin to read VSYS
• GPIO24 OP/IP wireless SPI data/IRQ
• GPIO23 OP wireless power on signal
• WL_GPIO2 IP VBUS sense – high if VBUS is present, else low
• WL_GPIO1 OP controls the on-board SMPS power save pin (Section 3.4)
• WL_GPIO0 OP connected to user LED

Apart from GPIO and ground pins, there are seven other pins on the main 40-pin interface:

• PIN40 VBUS
• PIN39 VSYS
• PIN37 3V3_EN
• PIN36 3V3
• PIN35 ADC_VREF
• PIN33 AGND
• PIN30 RUN
