Radianite-Buddy2: common questions

What microcontroller does the Radianite-Buddy2 use?

The Radianite-Buddy2 is built around the ESP32-S3R8, from the ESP32 family.

How big is the Radianite-Buddy2 PCB?

The Radianite-Buddy2 measures 20 × 52 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Radianite-Buddy2?

58 components, from 39 distinct parts. The full bill of materials is listed on this page.

Where can I download the Radianite-Buddy2 design files?

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

Can I use the Radianite-Buddy2 design in my own project?

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

Can I test firmware for the Radianite-Buddy2 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.
