Automatic-Smoothie-Maker: common questions
What microcontroller does the Automatic-Smoothie-Maker use?
The Automatic-Smoothie-Maker is built around the ESP32-S3-WROOM-2, from the ESP32 family.
How big is the Automatic-Smoothie-Maker PCB?
The Automatic-Smoothie-Maker measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Automatic-Smoothie-Maker?
98 components, from 44 distinct parts. The full bill of materials is listed on this page.
Where can I download the Automatic-Smoothie-Maker design files?
From the gendeh/Automatic-Smoothie-Maker repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Automatic-Smoothie-Maker design in my own project?
The repository has no license, so all rights stay with gendeh. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Automatic-Smoothie-Maker 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.
