(ICT) In-Circuit Tester baseboard

Copyright (c) 2025 Antmicro

Overview

This project contains open hardware PCB design files for an In-Circuit testing (ICT) baseboard. The board is based on FTDI/FT4232H and exposes common IO interfaces to provide an easy way to program various boards. The board features Analog-to-Digital Converters (ADCs) and programmable GPIO expanters that allow to drive/read digital signals and perform voltage measurements. This allows to use the ICT baseboard with a number of adapter boards which expose the communication, ADC and GPIO interfaces on a set of spring-loaded needle probes arranged for a specific board-under-test.

The PCB design files for the ICT baseboard were prepared in KiCad 9.x.
