Overview
ElectrodePCB is an open-source printed circuit board by williamapardis, from the williamapardis/electrodePCB repository on GitHub. It is a 2-layer board of 53.3 × 53 mm with 20 parts on 20 nets, routed with 39 tracks and 16 vias.
It is built around the TMP119AIYBGR. Its parts include 9 resistors, 2 connectors, 1 capacitor, 1 IC and 1 switch.
Main components
1README
README.mdelectrodePCB
A convenient solution-circuit interface. The electrode printed circuit board (PCB) is a experimental utility with submersible application of electrochemistry in mind. The PCB is designed to fasten directly to a Blue Robotic (BR) Enclosure - 2" Cylindrical Locking Series - O-ring flanges. The front side (or wet side) of the PCB is a layout of gold plated pads that act as substrate for unique solution processed electrode materials. The back side (or dry side) internal to the BR enclosure hosts both passive and active circuitry, their respective layout and interconnection to circuit and electrodes thought a multi. pos. FPC cable.

Questions
How big is the ElectrodePCB PCB?
It measures 53.3 × 53 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ElectrodePCB use?
20 parts, built around the TMP119AIYBGR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ElectrodePCB KiCad files?
From the williamapardis/electrodePCB repository on GitHub, at the commit this page was made from: the board is electrodePCB/electrodePCB.kicad_pcb and its schematic electrodePCB/electrodePCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ElectrodePCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask williamapardis before reusing the design.
