This handy kit enables power to a USB device (Chromecast/Raspberry Pi/USB Fan/USB light/etc) to be turned on/off by a Raspberry Pi Pico or Pico W! The board can be used with either a Pico W for WiFi-enabled control or using a regular Pico when using sensors or button inputs. A great match for our squid button cables! Examples using CircuitPython are provided. Note: Requires soldering of Pico/PicoW (not supplied) and USB Type-A socket (supplied but unsoldered). Connectors * Micro USB* - Power input / USB Data connected to output USB Type-A Socket. * Micro USB* (Pico) - Power input / USB Data connected to Pico. * 3-in 0.1" pin header (GND/GP13/GP12). * 4-pin SH - I2C STEMMA QT/Qwiic compatible (GND/3v3/GP26/GP27). [*] The micro USB ports are intentionally back to back to prevent both being connected at the same time. Example usage * Simple push/slide switch at the end of a (long) cable, using internal pull-up on the Pico * Internal temperature sensor triggering a USB fan when reaching a temperature * I2C CO2 sensor triggering a light * Wireless controlled Sleep function for Chromecast/Monitor You can find example CircuitPython scripts on Github. Pins & power Power for the output USB ports is controlled using GP2 (high=on), the other pins have been chosen to increase the usefulness of the board for those who may want to take advantage of the alternate functions. GPxx Port Functions GP12 3-pin header UART0 TX / I2C0 SDA / SPI1 RX GP13 3-pin header UART0 RX / I2C0 SCL / SPI1 CSn GP26 4-pin SH A0 / SPI1 SCK / I2C1 SDA GP27 4-pin SH A1 / SPI1 TX / I2C1 SCL Please Note * FOR USE ONLY WITH 5 VOLT supplies and devices - Using anything else may damage your power supply/charger/USB devices and the USB Power Switch Pro board. * USB data lines are connected at all times to either Pico or Output USB port depending on which micro USB port is used.
