Sharp LV is an open-source printed circuit board by martinberlin, from the martinberlin/Sharp-LV repository on GitHub, published under the MIT licence. It is a 4-layer board of 69.7 × 44.7 mm with 53 parts on 96 nets, routed with 649 tracks and 106 vias.
It is built around the NRF52840-QIAA-R, RT9080-33GJ5 and TPS2113APW, with the USBLC6-2P6, 2450AT42E0100E and SM04B-SRSS-TB(LF)(SN)(P) among its other parts. Its parts include 21 capacitors, 8 resistors, 7 connectors, 5 ICs and 4 inductors. It belongs with the lEDs and displays boards and the nRF52 and nRF5x boards of this library.
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:

It measures 69.7 × 44.7 mm and has 4 copper layers, 1.6 mm thick.
53 parts, built around the NRF52840-QIAA-R, RT9080-33GJ5, TPS2113APW 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.
From the martinberlin/Sharp-LV repository on GitHub, at the commit this page was made from: the board is Sharp-LV.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.
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).
