About the SenseCam STCS2A rev1 PCB

SenseCam STCS2A rev1 is an open source Nordic nRF PCB design by Appiko, published on GitHub under the CERN-OHL-1.2 license. It is a 2-layer board measuring 65 × 26 mm, with 28 components from 23 distinct parts.

Its main chip is the MDBT42Q, from the Nordic nRF family. Other key parts include the TLV8802 and STCS2A. By type, the board carries 14 capacitors, 5 resistors, 4 ICs, 3 connectors, 1 transistor and 1 battery holder.

From the project

This repository contains all the KiCad based PCB design and related documentation for all the PCBs developed at Appiko.

This repo contains the Kicad PCB design of the first revision of SenseCam LED Flash driver board containing the STCS2A constant current LED driver IC. This board is designed to be driven by SenseCam_rev1 to provide enough current to drive the LEDs for a powerful flash.

SenseCam STCS2A rev1: common questions

What microcontroller does the SenseCam STCS2A rev1 use?

The SenseCam STCS2A rev1 is built around the MDBT42Q, from the Nordic nRF family.

How big is the SenseCam STCS2A rev1 PCB?

The SenseCam STCS2A rev1 measures 65 × 26 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SenseCam STCS2A rev1?

28 components, from 23 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the SenseCam STCS2A rev1 design files?

From the Appiko/sense_snap_hw repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the SenseCam STCS2A rev1 design in my own project?

Yes, under the terms of its CERN-OHL-1.2 license, which Appiko chose for the repository.

Can I test firmware for the SenseCam STCS2A rev1 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
