Overview

Sensorboard is an open-source printed circuit board by CameraNexus, from the CameraNexus/sitina1 repository on GitHub, published under the MIT licence. It is a 6-layer board of 71.5 × 63.6 mm with 426 parts on 523 nets, routed with 6,537 tracks and 777 vias.

It is built around the 74HC2G17GW, DS1843D+TRL and SYR838PKC, with the TPS72301DBV, XC6206P152MR and BAT54S among its other parts. Its parts include 190 capacitors, 132 resistors, 30 ICs, 22 diodes and 6 inductors.

Questions

How big is the Sensorboard PCB?

It measures 71.5 × 63.6 mm and has 6 copper layers, 0.85 mm thick.

What parts does the Sensorboard use?

426 parts, built around the 74HC2G17GW, DS1843D+TRL, SYR838PKC and TPS72301DBV. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Sensorboard KiCad files?

From the CameraNexus/sitina1 repository on GitHub, at the commit this page was made from: the board is hardware/sensorboard/pcb.kicad_pcb and its schematic hardware/gripflex-lh/gripflex.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Sensorboard design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
