Roomlight hw: common questions
What microcontroller does the Roomlight hw use?
The Roomlight hw is built around the STM32F103CBTx, from the STM32 family.
How big is the Roomlight hw PCB?
The Roomlight hw measures 47.4 × 41.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Roomlight hw?
68 components, from 31 distinct parts. The full bill of materials is listed on this page.
Where can I download the Roomlight hw design files?
From the MG-5/roomlight_hw repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Roomlight hw design in my own project?
Yes, under the terms of its GPL-3.0 license, which MG-5 chose for the repository.
Can I test firmware for the Roomlight hw without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
