Its main chip is the ESP32-S3-MINI-1-N8, from the ESP32 family. Other key parts include the ADS131E08IPAGR, TP4056, TLV9051IDBVR, TPS7A9101DSKR and LM2775QDSGRQ1. By type, the board carries 20 resistors, 10 ICs, 7 connectors, 6 diodes, 3 switches and 3 inductors.

It belongs with the power & battery, sensors and test & measurement designs in this gallery.

From the project

Measurement Setup to analyze multiple ferroelectric sensors simultaneously

Measurement setup to analyze up to eight charge sources (e.g. ferroelectric sensors) simultaneously.

The system connects up to 8 channels via two RJ45 connectors (4 sources per connector). The PCB is designed for mobile use — it can be strapped to a test person, runs on battery power, and transmits data in millivolts (mV) via WiFi at up to 2000 samples per second.

Multi-Ferro-DAQ: common questions

What microcontroller does the Multi-Ferro-DAQ use?

The Multi-Ferro-DAQ is built around the ESP32-S3-MINI-1-N8, from the ESP32 family.

How big is the Multi-Ferro-DAQ PCB?

The Multi-Ferro-DAQ measures 50 × 65 mm, has 4 copper layers and is 1.564 mm thick.

How many components are on the Multi-Ferro-DAQ?

116 components, from 42 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 Multi-Ferro-DAQ design files?

From the TUDA-MUST/Multi-Ferro-DAQ repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Multi-Ferro-DAQ design in my own project?

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

Can I test firmware for the Multi-Ferro-DAQ without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
