8 switches rf: common questions

What microcontroller does the 8 switches rf use?

The 8 switches rf is built around the ESP32-DEVKITC-32D, from the ESP32 family.

How big is the 8 switches rf PCB?

The 8 switches rf measures 180.4 × 147.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 8 switches rf?

47 components, from 13 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the 8 switches rf design files?

From the TR-JAYAVARDHAN-SINGH/UT-quiz-and-interactive-system repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the 8 switches rf design in my own project?

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

Can I test firmware for the 8 switches rf 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.
