Lcdboard
About the Lcdboard PCB
Lcdboard is an open source PCB design by daveshah1, published on GitHub under the MIT license. It is a 4-layer board measuring 85.5 × 79.5 mm, with 32 components from 13 distinct parts.
Other key parts include the MCP1825T-ADJE, H546UAN0.1 and ADS7924. By type, the board carries 17 resistors, 9 capacitors, 3 ICs and 3 connectors.
From the project
4k Mixed Reality headset
All of the hardware is designed in KiCad 4.0, in the spirit of open source.
- mainboard is the headset mainboard, containing the FPGA and processor. It is a 150x90mm 8-layer board with a minimum track/space of 4mil and a controlled impedance requirement. - camboard is the OV16825 camera subassembly - lcdboard is the Z5 Premium LCD subassembly - usbbase is a board that combines power, USB 2.0 data and Displayport into a USB-C connection, so openMixR can be used if your computer doesn't support USB-C.
