About the Integrator Array PCB
Integrator Array 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 42.3 × 128.8 mm, with 97 components from 7 distinct parts.
Other key parts include the 74HC4051 and TL072. By type, the board carries 36 capacitors, 36 resistors, 24 ICs and 1 connector.
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.
