Dspod esp32s3: common questions

What microcontroller does the Dspod esp32s3 use?

The Dspod esp32s3 is built around the XC6222B331MR-G, from the ESP32 family.

How big is the Dspod esp32s3 PCB?

The Dspod esp32s3 measures 26.4 × 41.7 mm, has 4 copper layers and is 1.5313 mm thick.

How many components are on the Dspod esp32s3?

48 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dspod esp32s3 design files?

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

Can I use the Dspod esp32s3 design in my own project?

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

Can I test firmware for the Dspod esp32s3 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.
