From the project

Opensource Potentiostat

A USB-controlled potentiostat/galvanostat for electrochemistry measurements.

This version of the hardware design uses a PCB with dimensions of 55.5 mm by 70 mm to fit an EMI-shielded extruded aluminum case (IP 54 rated). This board will also fit a similar watertight extruded aluminum case (IP 65 rated). The terminal block and surface mounted USB mini-B connector in the original tdstav3 design by Thomas Dobbelaere were replaced with IP 67 rated circular connectors for the USB and electrode cables.

Opensens: common questions

What microcontroller does the Opensens use?

The Opensens is built around the PIC16F1459-I/SO, from the PIC family.

How big is the Opensens PCB?

The Opensens measures 55.5 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Opensens?

66 components, from 30 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 Opensens design files?

From the genji0306/Opensens repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Opensens design in my own project?

The repository has no license, so all rights stay with genji0306. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Opensens without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
