Tester dock
About the Tester dock PCB
Tester dock is an open source PCB design by njcoburn, published on GitHub under the Apache-2.0 license. It is a 4-layer board measuring 100 × 80 mm, with 81 components from 24 distinct parts.
Other key parts include the SN74LVC244APW, OPA2320AID and ADS1115IDGSR. By type, the board carries 35 resistors, 28 connectors, 8 capacitors and 4 ICs.
It belongs with the sensors designs in this gallery.
From the project
OPENIMAGESENSOR - An open source image sensor.
Prepared 19 September 2026. Two editable KiCad 7 projects implement the provisional 40 × 40 mm carrier and a tester with an optical aperture. Engineering review prototype; not released for fabrication.
Your existing KiCad installation is sufficient (KiCad 7 or newer). Copy the entire hardware/carrier folder to Windows, or extract the accompanying openimagesensor-kicad-review.zip. Open these project files from KiCad's File → Open Existing Project:
