ANSHUMANDOCX/Desk-DisplayIt is a desk display made using an E ink display.
Desk Display is an open-source printed circuit board by ANSHUMANDOCX, from the ANSHUMANDOCX/Desk-Display repository on GitHub. It is a 2-layer board of 33.2 × 40 mm with 63 parts on 84 nets, routed with 483 tracks and 111 vias.
It is built around the ESP32-WROOM-32E, CH343P and ME6217C33M5G, with the RT9193-33GB, MBR0530 and SS8050 among its other parts. Its parts include 21 capacitors, 21 resistors, 6 diodes, 5 transistors and 4 ICs. It belongs with the lEDs and displays boards and the ESP32 boards of this library.
It is a desk display made using an E-Ink display.
I will be using the following components:
I want to make a display that can show anything, but for me, I want it to display the current day, date, and time, along with a To-Do list at the bottom.
What I want to do is have the program fetch the day, date, and time details from the Wi-Fi network the ESP32 is connected to. For the To-Do list, I will use a website hosted on the ESP32 server to update the data whenever I want.
The display won't be battery powered — although it can be — but I don't want that for now. It will be powered through USB-C. For that, I’ve also added a switch to disconnect the board from programming mode by turning off the CH343 IC.

It measures 33.2 × 40 mm and has 2 copper layers, 1.6 mm thick.
63 parts, built around the ESP32-WROOM-32E, CH343P, ME6217C33M5G and RT9193-33GB. 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 ANSHUMANDOCX/Desk-Display repository on GitHub, at the commit this page was made from: the board is PCB/Desk Display.kicad_pcb and its schematic PCB/Desk Display.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask ANSHUMANDOCX before reusing the design.
