Main rounded: common questions

What microcontroller does the Main rounded use?

The Main rounded is built around the LTC3111EMSEPBF, from the ESP32 family.

How big is the Main rounded PCB?

The Main rounded measures 129.5 × 50.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Main rounded?

31 components, from 29 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Main rounded design files?

From the rompasaurus/dilder repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Main rounded design in my own project?

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

Can I test firmware for the Main rounded 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.
