Overview

S23-DB is an open-source printed circuit board by Cipulot, from the Cipulot/S23-DB repository on GitHub. It is a 2-layer board of 50 × 21.3 mm with 10 parts on 9 nets, routed with 42 tracks and 20 vias.

It is built around the S4B-ZR-SM4A-TF(LF)(SN). Its parts include 2 resistors, 1 capacitor, 1 connector and 1 inductor. It belongs with the keyboards and input and interfaces and adapters boards of this library.

S23 DB

S23 DB PCB render

S23 daughterboard with CC resistors.

There's not much to be said about this board. It's a daughterboard for the S23 by Sho, with the CC resistors to allow full USB-C operations.

The original JST ZH/ZR connector is replaced with one that has horizontal mount anchor points, to avoid mechanical stress on the connector (LCSC part number C485354).

The pinout is marked on the bottom of the PCB for reference.

Questions

How big is the S23-DB PCB?

It measures 50 × 21.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the S23-DB use?

10 parts, built around the S4B-ZR-SM4A-TF(LF)(SN). 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 S23-DB KiCad files?

From the Cipulot/S23-DB repository on GitHub, at the commit this page was made from: the board is PCB/S23_DB.kicad_pcb and its schematic PCB/S23_DB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the S23-DB design in my own project?

Its repository states no licence, so its author keeps all rights: ask Cipulot before reusing the design.
