ONOFF SNZB-01 Zigbee Wireless Switch is a mini and exquisite ZigBee wireless smart switch replying on SONOFF ZigBee Bridge that allows you to reach the purpose of scene linkages between ZigBee devices (SONOFF BASICZBR3 DIY smart switch and S31 Lite zb smart plug) and Wi-Fi devices. The button switch is customizable with three control options - single, double press and long press, so you can, pretty easily, program routines and actions as simple as you require. One-tap pairing. It’s so much easier to pair it with multiple connected devices that you want to manage, just tap on the APP to get all devices paired. The brilliance of the button lines in its flexible movability, you can strategically place it or move it around your house to where it will be most helpful, then create a smart scene to make it work for you based on different button actions that you customized. Two-way control is even available for you to turn on/off the light from two locations. The button is battery-operated that your mobile phone will receive a low-battery notification when the remaining battery level is less than 10%, maybe it’s time to change the battery. Note: 1. Do not install on the metal surface, otherwise it will affect the wireless communication distance. 2. The installation height of less than 2 m is recommended. 3.The device can be operated intelligently via working with the SONOFF ZigBee Bridge to communitcate with other devices.

Give your Raspberry Pi Pico project the capacity to chat with 2.4GHz Wi-Fi networks plus a handy microSD card slot!
Pico Wireless Pack attaches to the back of your Pico and uses an ESP32 chip to let your Pico connect to 2.4GHz wireless networks and transfer data. There's a microSD card slot for if you want to store lots of data locally as well as a RGB LED (for status updates) and a button (useful for things like enabling/disabling Wi-Fi).
Great for quickly adapting an existing Pico project to have wireless functionality, Pico Wireless Pack would come in handy for sending sensor data into home automation systems or dashboards, for hosting a web page from a matchbox or for letting your Pico interact with online APIs.
Raspberry Pi Pico not included - click here if you'd like to buy one.
Features
- ESP32-WROOM-32E module for wireless connectivity (connected via SPI) (datasheet)
- 1 x tactile button
- RGB LED
- Micro-SD card slot*
- Pre-soldered female headers for attaching your Raspberry Pi Pico
- Fully assembled
- No soldering required (as long as your Pico has header pins attached).
- Compatible with Raspberry Pi Pico.
- Dimensions: approx 53mm x 25mm x 11mm (L x W x H, including headers and components)
- C++ and MicroPython libraries
Getting started
We've added C++/MicroPython support for Wireless Pack to our Pico libraries and our custom MicroPython uf2 comes with wireless drivers for the ESP32 baked in. You can find C++ examples here and MicroPython examples here - there's a Cheerlights example that shows you how to make requests from an API, and one that sets your Pico up as a tiny HTTP server, accessible through your browser.
Alternatively, you can use Pico Wireless Pack with CircuitPython and Adafruit's easy to use ESP32SPI and Adafruit_CircuitPython_SD libraries. You'll need to alter their examples to use the correct pins:
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
Pinout
Notes
- * Please note that SD card support in the C++ SDK is still quite experimental - if you're planning on doing things with data you might have an easier time of it if you use CircuitPython!
- The cuttable traces on the back let you disconnect functions that you're not using, freeing up the pins and making it easier to use Wireless Pack with other add-ons.
