Homectrl rB: common questions
What microcontroller does the Homectrl rB use?
The Homectrl rB is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.
How big is the Homectrl rB PCB?
The Homectrl rB measures 85.2 × 84.7 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Homectrl rB?
108 components, from 72 distinct parts. The full bill of materials is listed on this page.
Where can I download the Homectrl rB design files?
From the jeevan9s/homectrl-sys repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Homectrl rB design in my own project?
The repository has no license, so all rights stay with jeevan9s. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Homectrl rB 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.
