About the Mood-Display PCB

Mood-Display is an open source ESP32 PCB design by Axe-1st, published on GitHub. It is a 2-layer board measuring 70.2 × 70.2 mm, with 54 components from 24 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N16R2, from the ESP32 family. Other key parts include the AMS1117-3.3, BMI270 and DRV2605LDGST. By type, the board carries 17 resistors, 15 capacitors, 7 diodes, 5 switches, 4 ICs and 4 connectors.

It belongs with the displays & leds and wearables designs in this gallery.

From the project

A Round Pin badge display! Powered by esp32c3 and a 1.28 in round display MoodBadge clips easily to your ID lanyard, keychain, belt, Bag, and so many more. You can easily express your mood or any animations you want to play on the display!

- 3rd Step: Get your solder paste then manualy little solder to each pad that needs a connection. Also have a tissue nearby! > Remember Patience is better than Crashing Out!

- 4th step: Start placing the compoments then when you are ready, use a hot plate to reflow all of the connections! > For this part you would be Placing compoments at the back of the pcb so that means the front side of the pcb is facing flat on the hotplate > When reflowing feel free to gently adjust the possiton of the compoments!

Mood-Display: common questions

What microcontroller does the Mood-Display use?

The Mood-Display is built around the ESP32-S3-WROOM-1-N16R2, from the ESP32 family.

How big is the Mood-Display PCB?

The Mood-Display measures 70.2 × 70.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mood-Display?

54 components, from 24 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 Mood-Display design files?

From the Axe-1st/Mood-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 Mood-Display design in my own project?

The repository has no license, so all rights stay with Axe-1st. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Mood-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.
