About the Readout 30pin bottom PCB

Readout 30pin bottom is an open source PCB design by opentac, published on GitHub under the MIT license. It is a 2-layer board measuring 16 × 22.7 mm, with 19 components from 10 distinct parts.

Other key parts include the TLV9362IDDFR, ADG706BRUZ, 74HC595BQ and LM2776DBVR. By type, the board carries 8 capacitors, 5 ICs, 3 connectors and 3 resistors.

It belongs with the sensors and robotics & motion designs in this gallery.

From the project

OpenTac: open tools to design, fabricate, read and simulate flex-PCB tactile skins that sense normal and shear force, for any robot surface.

Reads one OpenTac sensor of up to 15 rows x 15 columns. It is two small boards stacked on 1.27 mm 7-pin header/socket pairs: the top board has the microcontroller, the bottom board has the analog front end and the sensor connector.

Footprints, symbols and 3D models it uses are in hardware/libs. - production/: the JLCPCB fabrication files exported from this design on 2026-10-15: Gerber zip, JLCPCB BOM (bom.csv), pick-and-place positions (positions.csv), and the optional designator list and netlist.ipc. - bom.csv: the same BOM…
