Eja onboard gateway electronics: common questions

What microcontroller does the Eja onboard gateway electronics use?

The Eja onboard gateway electronics is built around the ESP32-DEVKITC-32D, from the ESP32 family.

How big is the Eja onboard gateway electronics PCB?

The Eja onboard gateway electronics measures 134.1 × 62.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Eja onboard gateway electronics?

21 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Eja onboard gateway electronics design files?

From the leonardoward/eja-onboard-gateway-electronics repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Eja onboard gateway electronics design in my own project?

Yes, under the terms of its Apache-2.0 license, which leonardoward chose for the repository.

Can I test firmware for the Eja onboard gateway electronics 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.
