Version History
0.3: stable release with momentary switch for wifi confifuration
0.4: In progress rename to BioElectric sensor, add resistors between probes; need to fix names, add branding and BOM
Overview
This uses the ADS1115 analog to digital inoutm 4 channels, low voltage a SSD 1306 OLED screen, Lolin D32 Pro, power led + resistor, and two switches for simple data capture and sending over OSC.
Kicad design with Gerber files.
Hardware
The hardware is a number of circuit board, designed in Kicad, that can be manufactured with some standard components.

Questions
How big is the BioElectric PCB?
It measures 42.4 × 133.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BioElectric use?
18 parts, built around the ADS1115 and B3B-XH-A(LF)(SN). 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 BioElectric KiCad files?
From the BioSymphonic/BioSymphonic_BioElectric_Node repository on GitHub, at the commit this page was made from: the board is BioElectric.kicad_pcb and its schematic BioElectric.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BioElectric design in my own project?
Its repository states no licence, so its author keeps all rights: ask BioSymphonic before reusing the design.
