Welcome to the breezybox wiki! Welcome to the breezydemo wiki!

This is a fork of valdanylchuk's breezybox. This notice is here to distinguish a fork clearly from the original.

Intro:

I discovered breezybox on Feb 1 2026. I have a room in the back of my house that doubles as office space and electronics lab, with boxes of parts stacked on other boxes of parts. I have an entire workbench dedicated to breadboard work, prototyping and soldering.

I'm a well informed hobbiest with respect to electronics. I have a general class HAM operator's license. I also have licenses to operate GMRS and Marine radio transceivers. Professionally, I'm a programmer/admin with a few decades of experience. I spend most of my time working on mundane python stuff.

I became interested in ESP 32 specifically to do work like this. Now I have found someone has laid the ground work already, which is fantastic. Its so much work I don't have to do.

To Valdanylchuk I say, 'Thank you'.

Very briefly, the ESP32 generally is a microcontroller unit, or MCU. There are dozens of kinds of ESP32 devices that do many things. The ESP32-S3 especially is very capable, and can be expanded. Additionally, they have support for SDXC high capacity solid state storage, and full USB and WIFI support. Given the ready adaptation of peripherals via USB, and the ready integration of SPI LED displays, I've often wondered would it be possible to port BUSYBOX to it. Not necessarily because I'm attached to busybox, but to get that functionality.

That said, I would welcome that functionality dressed natively, if you will, and breezybox, I think, delivers.

I'm going to document my experience with it here, starting with crafting this journalistic wiki.

The first steps, of course, are to clone valdanylchuk's repository, and so here we are :)

0530 Wondering if the arduino R4 I have ready to go with a small touchscreen is adequate to the task of exploring the breezybox binary. I don't think it does the SD Card, which is a core requirement for me. Investigations will ensue. If not, I'll resume my screen adaptation work in progress. If all else fails and I get real itchy there's always the waveshare device on amazon for ~50$

My ongoing WIP adapting some displays might actually be useful, if awkward; as I recall, I have the display part working on a breadboard, but I would need to get the sdcard slot wired up as well, though I have not yet found where valdanychuk approaches concerns around filesystems.

Perhaps my insistence upon having the sdcard available is more timely from a support perspective than as a concern over functional resource availability.
