About the Current sensor filter PCB

Current sensor filter is an open source STM32 PCB design by Synthron, published on GitHub. It is a 4-layer board measuring 160 × 100 mm, with 91 components from 33 distinct parts.

Its main chip is the STM32F103C8Tx, from the STM32 family. Other key parts include the ACS723xLCTR-05AB, LM2904 and AP1117-33. By type, the board carries 37 capacitors, 29 resistors, 10 connectors, 7 ICs, 5 inductors and 2 transistors.

It belongs with the audio, displays & leds and sensors designs in this gallery.

From the project

Modular Electronics Workstation

The ModLab is designed to be housed in a 19" Rack with 3U. It is the improved version of the (failed) Arduino Workstation I built a long time ago.

But now It will be bigger, better and way too complicated.

Current sensor filter: common questions

What microcontroller does the Current sensor filter use?

The Current sensor filter is built around the STM32F103C8Tx, from the STM32 family.

How big is the Current sensor filter PCB?

The Current sensor filter measures 160 × 100 mm, has 4 copper layers and is 4.69 mm thick.

How many components are on the Current sensor filter?

91 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the Current sensor filter design files?

From the Synthron/ModLab repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Current sensor filter design in my own project?

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

Can I test firmware for the Current sensor filter without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
