Pico Base Expansion Boards for Raspberry Pi RPI Pico

The PTSolns Pico Base and Pico Base + Proto are intended to interface with the Raspberry Pi Pico family (henceforth referred to as Pico), offering much convenience. While mounted in the Pico Base, the Pico can be powered in multiple ways. Onboard protection prevents current from going into a battery (if connected via the female jack or the 2-pin screw terminal) while power is supplied by the onboard Pico USB connection. The user can switch between power sources without interrupting their circuit or the Pico. The board also offers a reset button as well as a power LED. An onboard logic level shifter allows for the simultaneous operation of both 3.3 V and 5 V I^²C peripherals. There are screw terminal and header connections for both 3.3 V and 5 V I²C ports, as well as the common QWIIC^® connector.

The Pico Base + Proto has additional features. Suitably located adjacent to the 5 V I^²C connectors, the 1602 and 2004 LCD mounting interface lets the user easily add an LCD to their project. The Pic Base + Proto board also has two programmable buttons and two programmable LEDs. The prototyping section has three power rails at the top, one at the center, and another three at the bottom. These rails can be configured for multiple uses and by default are not connected to 3.3 V, 5 V, and GND. The user can solder the corresponding jumper pads to electrically connect the rails to 3.3 V, 5 V, and GND. The prototyping section consists of electrically connected rows of five through-holes, laid out in a traditional breadboard pattern, with a total of 300 tie points. Three unique rows made up of teardrop-shaped soldering pads allow the user to easily connect adjacent rows of five. The onboard SOIC interface has a breakout running immediately adjacent to the prototyping section.
