The purpose of this board is to make it quick and easy to get Raspberry Pi Pico projects up and running. It's a step up from just plugging the Pico into a breadboard. The key features are:

• Labelling: All the pins are labelled with their physical pin numbers and key function - eg, GND, GP7 etc.
• Reset button: A surface-mount tactile button pulls the RUN signal low to perform a board reset.
• 8 buffered 5V inputs: A buffer chip provides level shifting down from +5V to +3V3. Header pins allow you to connect any of these inputs to any of the Pico's GPIOs at a safe voltage.
• 8 buffered 5V outputs: Another buffer chip shifts signals up from +3V3 to +5V, allowing the Pico to work with 5V devices such as sensors, actuators etc. Again, header pins allow you to connect any of these inputs to any of the Pico's GPIOs.
• 8 LEDs: The outputs of the buffer chip have LEDs showing the signal state of connected devices, or you can just use the LEDs for debugging or output purposes.
• I2C port: The I2C0 port is broken out to four header pins (SDA, SCL, +3V3 and GND). The order of the pins is compatible with many small OLED modules. The SDA and SCL lines have 4.7kΩ pullup resistors.
• Dual Pico footprint: The footprint for the Pico accommodates mounting it either directly soldered as a surface-mount device or via headers, so you can have the Pico permanently attached or removeable. The footprint also has a keepout area ensuring there are no copper layers or traces under the antenna area.

The board is designed to be powered via the USB on the Pico, although you could connected +5V directly to the Pico's VSYS pin.

This is a 4-layer board with dedicated GND and +3V3 planes on the inner layers.

Four mounting holes are provided, suitable for M3 hardware.

The BOM includes all surface-mount components, to which you’ll need to add 2.54mm-pitch header pins and the Pico board of your choice.
