The purpose of this project is to develop a piece of artisan eletronics to serve as a prize for an eletronics competition. The design consists of a PCB and 3D-printed case. The CAD model for the case has been excluded from this project because it incorporates proprietary elements.
Development Tools Arduino IDE KiCAD FreeCAD
The J3 header has a 1:1 pinout matching the Attiny85 processor. Instructions for programming the Attiny85 using an Arduino is documented at the start of the Arduino code. Once the Arduino has been programmed with the ArduinoAsISP program, it can be connected to the J3 programming header using the following connections: https://hackster.imgix.net/uploads/cover_image/file/50546/Programming%20ATtiny85%20with%20Arduino%20Uno_bb.png?auto=compress%2Cformat&w=900&h=675&fit=min

Questions
How big is the Pendant pcb PCB?
It measures 50.8 × 67.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pendant pcb use?
35 parts, built around the TPA6211A1DGNR, SK6812, S2B-PH-SM4-TB(LF)(SN) and 10118193-0001LF. 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 Pendant pcb KiCad files?
From the scottalmond/Pendant repository on GitHub, at the commit this page was made from: the board is src/pcb/pendant_pcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pendant pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask scottalmond before reusing the design.
