README
README.mdSSD2828-DEV
A collection of boards to test the SSD2828 RGB to MIPI Converter with the LH154Q01 panel by AUO and the VS035ZSM by BOE. The boards are meant to be ordered as a single unit and then be separated using a box cutter ( the dust generated by cutting cutting FR4 is carcenogenic PLEASE be carefull! ).
The pcb
The pcb is designed using the JLC04161H-7628 stackup by JLCPCB. The MIPI DSI protool requires controlled impedance traces to function properly (100Ω differental, 50Ω single ended), depending on the provided pcb stackup different trace widths and spacings need to be selected. Additionally the signals must be kept away from noise sources such as inductors and other signals. When switching layers with MIPI signals, GND vias need to be placed near the signal vias.
LH154Q01 panel
The LH154Q01 panel has been tested and is working correctly.
The panel does not support packed pixel stream packets, the only way to send pixel data to the display, is through DCS commands. in this demo, a STM32f401 is sending the the write_memory_continue(0x3C) DCS command containing pixel data, through SPI to the SSD2828.
VS035ZSM panel
The VS035ZSM panel has been tested and is working correctly.
The panel gets initialized on MIPI LP mode and the video is transmitted MIPI HS mode @912Mbps per lane. The ssd2828 is generating the test video signal called BIST. The panel has 8-bit color depth, reaning each pixel requires 24bits. The resolution of the panel is 1400x1600, including the porch values the total resoution is 1470 x 167. To operate at 60fps, 1470 x 1670 x 24 x 60 = 3.53Gbps are required resulting at 883Mbps per lane. The panel also suppors VESA DSC making 90fps operation possible. Unfortunately the SSD2828 does not include a DSC encoder.

Questions
How big is the Ssd2828 board PCB?
It measures 91.3 × 53.5 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Ssd2828 board use?
144 parts, built around the LP3320B6F, PAM2306DYPAA, TLV62568DBVR-TP and TPS65131TRGERQ1. 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 Ssd2828 board KiCad files?
From the dartcom/ssd2828-dev repository on GitHub, at the commit this page was made from: the board is hardware/ssd2828_board.kicad_pcb and its schematic hardware/LH154Q01.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ssd2828 board design in my own project?
Its repository states no licence, so its author keeps all rights: ask dartcom before reusing the design.
