Persistence of Vision is a fundamental principle that allows our eyes to perceive continuous motion from separate images, a concept crucial to the illusion of motion in cinema. When I was a kid, I was always fascinated with it. So, in this project, we are going to use this fascinating optical phenomenon to create a cool-looking POV Display. You must have seen a lot of such projects on the web, but most of them are limited to very low resolution and just display some texts and geometries. We plan to create a…

POV-Display: common questions

What microcontroller does the POV-Display use?

The POV-Display is built around the ESP32-WROOM-32D, from the ESP32 family.

How big is the POV-Display PCB?

The POV-Display measures 208 × 58 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the POV-Display?

324 components, from 27 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the POV-Display design files?

From the Circuit-Digest/POV-Display repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the POV-Display design in my own project?

The repository has no license, so all rights stay with Circuit-Digest. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the POV-Display without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
