Sharp Memory Display PCB - alternative design for 3.3v only.. Based on mechanical layout from the Adafruit 3502 module ( https://github.com/adafruit/Adafruit-Sharp-Memory-Display-PCBs ).
SharpDisplayPcb is an open-source printed circuit board by GerardoNevarez, from the GerardoNevarez/SharpDisplayPcb repository on GitHub. It is a 2-layer board of 34 × 39 mm with 15 parts on 9 nets, routed with 96 tracks and 5 vias.
It is built around the MH3. Its parts include 4 capacitors, 2 connectors and 1 resistor. It belongs with the lEDs and displays boards of this library.
Replacement PCB for the Adafruit SHARP Memory Display Breakout (3502). Only for 3.3V.

It measures 34 × 39 mm and has 2 copper layers, 1.6 mm thick.
15 parts, built around the MH3. 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.
From the GerardoNevarez/SharpDisplayPcb repository on GitHub, at the commit this page was made from: the board is SharpDisplayPcb/SharpDisplayPcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask GerardoNevarez before reusing the design.
