Pico Wireless Pack

Add 2.4 GHz Wi-Fi connectivity and local storage to your Raspberry Pi Pico with this compact add-on pack. The Pico Wireless Pack attaches to the back of your Pico using pre-soldered female headers — no soldering required (as long as your Pico has header pins attached).

Powered by an ESP32-WROOM-32E module connected via SPI, this pack lets your Pico connect to wireless networks and transfer data. It also includes a microSD card slot for local data storage, an RGB LED for status indication, and a tactile button.

Key Features

• ESP32-WROOM-32E – 2.4 GHz Wi-Fi connectivity via SPI
• MicroSD Card Slot – Store data locally
• RGB LED – Visual status indicator
• Tactile Button – Useful for enabling/disabling Wi-Fi or triggering actions
• Pre-Soldered Headers – Plug-and-play attachment to Pico
• Cuttable Traces – Disconnect unused functions to free up pins for other add-ons
• Dimensions – Approximately 53 × 25 × 11 mm (L × W × H, including headers)

Ideal For

• Sending sensor data to home automation systems or dashboards
• Hosting a simple web server from your Pico
• Interacting with online APIs
• Adding wireless functionality to existing Pico projects

Getting Started

Pimoroni provides C++ and MicroPython support through their Pico libraries, with a custom MicroPython UF2 that includes wireless drivers for the ESP32. For CircuitPython, you can use Adafruit's ESP32SPI and SD libraries with the following pin configuration:

spi = busio.SPI(board.GP18, board.GP19, board.GP16)

esp32_cs = DigitalInOut(board.GP7)
esp32_ready = DigitalInOut(board.GP10)
esp32_reset = DigitalInOut(board.GP11)

SD_CS = board.GP22
