Dongle eaLIVE: common questions

What microcontroller does the Dongle eaLIVE use?

The Dongle eaLIVE is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Dongle eaLIVE PCB?

The Dongle eaLIVE measures 45 × 55 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dongle eaLIVE?

69 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dongle eaLIVE design files?

From the joaogabrielsantosD/Dongle-eaLIVE-PCB repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Dongle eaLIVE design in my own project?

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

Can I test firmware for the Dongle eaLIVE 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.
