This 60-electrode microelectrode array (MEA) PCB is designed for high-resolution in vitro signal acquisition. It features:

60 tightly spaced electrodes (700 µm pitch)

Gold-plated pads for optimal biocompatibility and low impedance

Central well zone compatible with standard culture chambers

High signal integrity routing for electrophysiology and burst detection

Designed for DIY or research-grade setups

The array is ideal for:

Culturing and recording

Projects involving closed-loop feedback, spike sorting, or neural learning systems

Integrating with systems like ADS1299, OpenBCI, or custom amplifiers

This board is currently used in real lab experiments and tested with rat cortical neurons. It’s open-hardware friendly and can be adapted to your setup.
