Phase3-manager: common questions

What microcontroller does the Phase3-manager use?

The Phase3-manager is built around the ESP32-S3-WROOM-1-N8R2, from the ESP32 family.

How big is the Phase3-manager PCB?

The Phase3-manager measures 100 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Phase3-manager?

80 components, from 37 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 Phase3-manager design files?

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

Can I use the Phase3-manager design in my own project?

Yes, under the terms of its GPL-3.0 license, which udaravima chose for the repository.

Can I test firmware for the Phase3-manager 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.
