Controller
About the Controller PCB
Controller is an open source PCB design by wrochira, published on GitHub under the CC-BY-NC-4.0 license. It is a 4-layer board measuring 69.6 × 56.4 mm, with 32 components from 13 distinct parts.
Other key parts include the 74HC4051, AD5689RXRUZ, TL072 and AD7689XCP. By type, the board carries 10 resistors, 6 ICs, 6 connectors, 6 capacitors and 4 switches.
From the project
A dual-board hybrid analog–digital computing prototype using op-amp integrators and a Raspberry Pi Pico controller.
This project is a proof-of-concept hybrid computing system built from two PCBs: an integrator array board with 18 analog op-amp integrators, and a controller board built around a Raspberry Pi Pico, high‑precision ADC/DACs, and multiplexers. The intent is to represent three particles in 3D space (acceleration → velocity → position per dimension), with the Pico reading integrator outputs, computing forces, and writing updated accelerations back into the analog system.

Controller: common questions
How big is the Controller PCB?
The Controller measures 69.6 × 56.4 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Controller?
32 components, from 13 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Controller design files?
From the wrochira/hybrid-integrator-array repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Controller design in my own project?
It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.
