Chama-se Raspberry Pi Pico W e é a nova placa da Raspberry Foundation.

Esta placa é baseada no chip microcontrolador RP2040 e foi desenhada para ser uma plataforma de desenvolvimento de baixo cuso. Diferente da Raspberry Pi Pico normal esta placa disponibiliza uma interface Wireless de 2.4GHc (Wi-Fi 802.11n).

Description

Raspberry Pi Pico W adds on-board single-band 2.4GHz wireless interfaces (802.11n) using the Infineon CYW4343 while retaining the Pico form factor. The on-board 2.4GHz wireless interface has the following features:

  1. Wireless (802.11n), single-band (2.4 GHz)

  2. WPA3

  3. Soft access point supporting up to four clients

The antenna is an onboard antenna licensed from ABRACON (formerly ProAnt). The wireless interface is connected via SPI to the RP2040 microcontroller.

Due to pin limitations, some of the wireless interface pins are shared. The CLK is shared with VSYS monitor, so only when there isn’t an SPI transaction in progress can VSYS be read via the ADC. The Infineon CYW43439 DIN/DOUT and IRQ all share one pin on the RP2040. Only when an SPI transaction isn’t in progress is it suitable to check for IRQs. The interface typically runs at 33MHz.

For best wireless performance, the antenna should be in free space. For instance, putting metal under or close by the antenna can reduce its performance both in terms of gain and bandwidth. Adding grounded metal to the sides of the antenna can improve the antenna’s bandwidth.
