LiquorBot: common questions

What microcontroller does the LiquorBot use?

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

How big is the LiquorBot PCB?

The LiquorBot measures 58.5 × 87 mm, has 4 copper layers and is 1.58 mm thick.

How many components are on the LiquorBot?

36 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the LiquorBot design files?

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

Can I use the LiquorBot design in my own project?

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

Can I test firmware for the LiquorBot 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.
