🍪 Crumbs - Collection of my DIY Electronic Module

- 16 Februari 2026, make a prototype board, but not sure why its not able detected in pc. need to recheck schematic and re make the prototype board.

ESP32-S3-tempel: common questions

What microcontroller does the ESP32-S3-tempel use?

The ESP32-S3-tempel is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the ESP32-S3-tempel PCB?

The ESP32-S3-tempel measures 70.4 × 51.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-S3-tempel?

35 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32-S3-tempel design files?

From the ahsanu123/crumbs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESP32-S3-tempel design in my own project?

Yes, under the terms of its MIT license, which ahsanu123 chose for the repository.

Can I test firmware for the ESP32-S3-tempel 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.
