README
S3-silicon-Sharp-Touch/README.mdSHARP Light and Versatile controller
The goal of this PCB is to make a small SHARP memory in pixel (MIP) controller All this might change as the idea develops but initially the plan is the following:
- DS3231 or RV2032 acting as RTC to generate the Squarewave required by this displays
- Optional touch only available in eBay from a seller in the UK (Better use 1.1 version)

Questions
How big is the S3-silicon Sharp Touch PCB?
It measures 77.9 × 45.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the S3-silicon Sharp Touch use?
66 parts, built around the ESP32-S3FN8, RT9080-33GJ5, TP4057-42-SOT26-R and USBLC6-2P6. 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 S3-silicon Sharp Touch KiCad files?
From the martinberlin/Sharp-LV repository on GitHub, at the commit this page was made from: the board is S3-silicon-Sharp-Touch/S3-silicon-Sharp-Touch.kicad_pcb and its schematic S3-silicon-Sharp-Touch/S3-silicon-Sharp-Touch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the S3-silicon Sharp Touch 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).
