About the ESPHome-DeskPI-Fan-Controller PCB

ESPHome-DeskPI-Fan-Controller is an open source ESP32 PCB design by mikaelholber, published on GitHub. It is a 4-layer board measuring 39 × 39 mm, with 39 components from 17 distinct parts.

Its main chip is the ESP32-S3-MINI-1, from the ESP32 family. Other key parts include the TLV76733DGNR and BME280. By type, the board carries 15 resistors, 11 capacitors, 3 ICs, 2 diodes and 1 fuse.

It belongs with the iot & wireless and sensors designs in this gallery.

From the project

My minilab is located in the bedroom and tucked away in such a way that I need good airflow at the lowest possible noise. To achive this i decided to use ESPHome to control a few 5V fans which can be mounted in the vented blanks available.

The schematics and ESPHome configuration is derived from https://github.com/patrickcollins12/esphome-fan-controller and the only original work is the PCB layout to fit the specific envelope in the vented blank.

ESPHome-DeskPI-Fan-Controller: common questions

What microcontroller does the ESPHome-DeskPI-Fan-Controller use?

The ESPHome-DeskPI-Fan-Controller is built around the ESP32-S3-MINI-1, from the ESP32 family.

How big is the ESPHome-DeskPI-Fan-Controller PCB?

The ESPHome-DeskPI-Fan-Controller measures 39 × 39 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESPHome-DeskPI-Fan-Controller?

39 components, from 17 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 ESPHome-DeskPI-Fan-Controller design files?

From the mikaelholber/ESPHome-DeskPI-Fan-Controller 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 ESPHome-DeskPI-Fan-Controller design in my own project?

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

Can I test firmware for the ESPHome-DeskPI-Fan-Controller 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.
