🤖 LiquorBot

Automatic liquor dispensing machine used for pouring several-layer shots.

The project uses a stepper motor, liquid pumps, Hall sensor, optocouplers and LEDs controlled by the Esp32 microcontroller.

Most of the case parts were printed on a 3D printer.

Questions

How big is the LB MBoard PCB?

It measures 58.5 × 87 mm and has 4 copper layers, 1.58 mm thick.

What parts does the LB MBoard use?

46 parts, built around the ESP32-S3-WROOM-1-N16R2, AP2210K-5.0TRG1, LM1117DT-3.3 and SRV05-4. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the LB MBoard KiCad files?

From the irozalski/LiquorBot repository on GitHub, at the commit this page was made from: the board is KiCad files/LB_MBoard.kicad_pcb and its schematic KiCad files/LB_MBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the LB MBoard design in my own project?

Its repository states no licence, so its author keeps all rights: ask irozalski before reusing the design.
