## Description

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.

**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/Qwick 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 (see "Source Code" link below).

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 those who may want to talk 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 |
| GP2 | Internal | USB Power Switch |

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.

**Options**

- Kit :: Requires soldering of Pico/PicoW (not supplied) and USB Type-A socket (supplied unsoldered).
- Assembled W :: Supplied fitted with a Raspberry Pi Pico W
