About the Tdstatv3 PCB

Tdstatv3 is an open source PIC PCB design by thomasdob, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 50 × 50 mm, with 71 components from 32 distinct parts.

Its main chip is the PIC16F1459, from the PIC family. Other key parts include the LM2662, ADR421, MCP3550, DAC1220 and OPA4192. By type, the board carries 29 capacitors, 21 resistors, 9 ICs, 4 relays, 4 diodes and 3 connectors.

It belongs with the power & battery designs in this gallery.

From the project

A USB-controlled potentiostat/galvanostat for thin-film battery characterization

This assumes that the current user is a member of the plugdev group, and that the default USB Vendor and Product ID's as coded in the microcontroller firmware are used; if not, these values need to be adjusted.

Tdstatv3: common questions

What microcontroller does the Tdstatv3 use?

The Tdstatv3 is built around the PIC16F1459, from the PIC family.

How big is the Tdstatv3 PCB?

The Tdstatv3 measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tdstatv3?

71 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the Tdstatv3 design files?

From the thomasdob/tdstatv3 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Tdstatv3 design in my own project?

Yes, under the terms of its GPL-3.0 license, which thomasdob chose for the repository.

Can I test firmware for the Tdstatv3 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.
