Selectable dice types: 1d2, 2d2, 1d4, 2d4, 1d6, 2d6, 1d8, 2d8, 1d10, 1d12, 1d100, 1d20.
Display will auto-shutoff after around 10s
MPLab X with XC8 toolchain used.
For the uC used (a PIC 16F88) after programming the chip the first time, Vpp first programming mode must be used to reflash firmware as the internal oscillator is used along with all available pins (MCLR).

Questions
How big is the DiceRoller PCB?
It measures 46 × 68 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DiceRoller use?
16 parts, built around the NTE3078. 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 DiceRoller KiCad files?
From the centicosm/DiceRoller repository on GitHub, at the commit this page was made from: the board is Kicad/DiceRoller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DiceRoller design in my own project?
Its repository states no licence, so its author keeps all rights: ask centicosm before reusing the design.
