Tubender: common questions

What microcontroller does the Tubender use?

The Tubender is built around the ESP32-WROOM-32UE_M113EH6400UH3Q0_, from the ESP32 family.

How big is the Tubender PCB?

The Tubender measures 352.3 × 159.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Tubender?

252 components, from 87 distinct parts. The full bill of materials is listed on this page.

Where can I download the Tubender design files?

From the smvumbaco/Tubender-FA24 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Tubender design in my own project?

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

Can I test firmware for the Tubender 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.
