About the Smart projector remote PCB

Smart projector remote is an open source ESP32 PCB design by benceharomi, published on GitHub under the MIT license. It is a 2-layer board measuring 30 × 60 mm, with 24 components from 16 distinct parts.

Its main chip is the ESP32-WROOM-32E-N16, from the ESP32 family. Other key parts include the CP2102N-A01-GQFN24 and BD33IC0MEFJ-CE2. By type, the board carries 9 resistors, 5 capacitors, 3 ICs, 3 transistors, 2 connectors and 1 switch.

It belongs with the iot & wireless, dev boards & breakouts and usb & debug tools designs in this gallery.

From the project

Transform your regular projector into a smart home device, enabling voice control and automation through Apple's HomeKit ecosystem.

This project transforms your regular projector into a smart home device, enabling voice control and automation through Apple's HomeKit ecosystem.

An ESP32-based device that can control projectors via infrared signals and integrates with Apple HomeKit. It allows you to control your projector using Siri voice commands, the Home app, or enable your projector to be added to scenes like "Movie time" or "Bed Time".

Smart projector remote: common questions

What microcontroller does the Smart projector remote use?

The Smart projector remote is built around the ESP32-WROOM-32E-N16, from the ESP32 family.

How big is the Smart projector remote PCB?

The Smart projector remote measures 30 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Smart projector remote?

24 components, from 16 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 Smart projector remote design files?

From the benceharomi/smart-projector-remote 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 Smart projector remote design in my own project?

Yes, under the terms of its MIT license, which benceharomi chose for the repository.

Can I test firmware for the Smart projector remote 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.
