About the Protocentral fdc2214 hardware PCB

Protocentral fdc2214 hardware is an open source PCB design by Protocentral, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 32 × 34.7 mm, with 27 components from 14 distinct parts.

Other key parts include the FDC2214RGHR, AP2112K-3.3 and BSS138DW-7-F. By type, the board carries 10 capacitors, 5 resistors, 4 connectors, 4 inductors, 3 ICs and 1 crystal.

It belongs with the dev boards & breakouts and test & measurement designs in this gallery.

From the project

KiCad hardware design files for the ProtoCentral FDC2214 4-channel capacitance-to-digital converter breakout (CERN-OHL-P v2).

Open-source hardware design files for the ProtoCentral FDC2214 4-Channel Capacitance-to-Digital Converter Breakout — a 4-channel, 28-bit capacitive-sensing board based on the Texas Instruments FDC2214.

The FDC2214 measures the resonant frequency of an external LC tank, an EMI-resistant technique that delivers femtofarad-level resolution. This board adds four onboard LC-tank inductors, dual Qwiic connectors, and a simple I²C interface.
