StreamBuddy: common questions

What microcontroller does the StreamBuddy use?

The StreamBuddy is built around the ATMEGA32U4, from the AVR/Arduino family.

How big is the StreamBuddy PCB?

The StreamBuddy measures 76.4 × 104.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the StreamBuddy?

55 components, from 17 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 StreamBuddy design files?

From the harshitgoel96/StreamBuddy repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the StreamBuddy design in my own project?

Yes, under the terms of its GPL-3.0 license, which harshitgoel96 chose for the repository.

Can I test firmware for the StreamBuddy without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
