This board sits on top of an MMC3 footprint so you can use the smaller SMD133 chip instead

This is the dumbest board I’ve ever made

This is the 3.3V analog output analog shaft encoder designed by FRC Team 4272. The intent of this encoder is to replace the CANcoder or CTRE mag encoder. The intent of this encoder is to go to the Spark MAX 3.3V analog input, for a clean wiring solution,

Raspberry Pi Pico Stripboard

A stripboard PCB designed for the Raspberry Pi Pico. Compatible with Pico W also.

Features

• Neatly sized to fit the Pico family of boards
• Reversible design—flip it any way you need
• Large ground plane

Purpose

Use this stripboard to permanently solder through-hole components to a Raspberry Pi Pico, designed for tidy, complete projects that don’t need a custom PCB. Unlike protoboards, the footprint of this stripboard matches the Pico’s within a couple tenths of a millimeter.

The stripboard has a breadboard-like layout of horizontal rows of holes connected to each other. Both the left and right sides have four holes per row, each. This allows up to three components to be soldered to each pin of the Pico. The rows connected to ground are an exception. Because the Pico’s ground pins are mirrored on the left and right sides, the rows connected to ground are connected all the way across the stripboard.

Aside from the ground rows, the traces between holes in the same row can be drilled or scratched out to separate the holes if needed.

Breakout for the LPC2101/2/3 microcontroller

Has a footprint for a 7404 SMT IC, which the original also used (in DIP form) to select the proper address range. The larger footprint is for a 2764 or 2864, most likely the original ROM from the original piggyback board. The smaller footprint is for either a dupont header (solder the corresponding gendered dupont header onto the mainboard) or machine pins.
