Pocket s: common questions

What microcontroller does the Pocket s use?

The Pocket s is built around the ESP32-S3-WROOM-1-N8R8, from the ESP32 family.

How big is the Pocket s PCB?

The Pocket s measures 85 × 52 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Pocket s?

28 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pocket s design files?

From the ridhinva/pocket-s repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Pocket s design in my own project?

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

Can I test firmware for the Pocket s 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.
