STRATOSDRONES: common questions

What microcontroller does the STRATOSDRONES use?

The STRATOSDRONES is built around the ESP32-P4NRW32, from the ESP32 family.

How big is the STRATOSDRONES PCB?

The STRATOSDRONES measures 38 × 74 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the STRATOSDRONES?

109 components, from 44 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 STRATOSDRONES design files?

From the equationstratos/STRATOSDRONES 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 STRATOSDRONES design in my own project?

Yes, under the terms of its MIT license, which equationstratos chose for the repository.

Can I test firmware for the STRATOSDRONES 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.
