From the project
This repository contains a single INA333/OPA2192/TLC555/LM386M-1 sonifier schematic. The PCB retains its manual footprint placement and has a provisional two-layer signal route with one PGND net and thermal-relief pours on both copper layers. Schematic parity and DRC remain open
This repository contains a single INA333/OPA2192/TLC555/LM386M-1 sonifier schematic. The PCB retains its manual footprint placement and has a provisional two-layer signal route with one PGND net and thermal-relief pours on both copper layers. Schematic parity and DRC remain open before fabrication.

Electrode: common questions
How big is the Electrode PCB?
The Electrode measures 72.4 × 27.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Electrode?
48 components, from 29 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 Electrode design files?
From the flintwinters/electrode 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 Electrode design in my own project?
The repository has no license, so all rights stay with flintwinters. Use it as a reference, and ask the author before reusing the design.
