RemoteHub: common questions

What microcontroller does the RemoteHub use?

The RemoteHub is built around the ESP32-C3-WROOM-02, from the ESP32 family.

How big is the RemoteHub PCB?

The RemoteHub measures 33 × 55 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RemoteHub?

26 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the RemoteHub design files?

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

Can I use the RemoteHub design in my own project?

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

Can I test firmware for the RemoteHub 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.
