From the project
A 24 inch Raspberry Pi-based Android digital picture frame attached to a 220W stereo Bluetooth speaker with DSP
AI Use: No AI was used to generate any journal entries at all. AI was only used for electronics help and parsing some really long chip datasheets
The SF_01 also has a total 220W RMS speaker system on board, with 6 3.5-inch bass-mid woofers, and 4 0.75-inch tweeterspointing outwards from all four corners.
The frame itself is 3D-printed, with a large stand secured by VESA mount screws driven into the back of the monitor.

SF 01 Compute Board: common questions
What microcontroller does the SF 01 Compute Board use?
The SF 01 Compute Board is built around the TPS54540DDAR, from the ESP32 family.
How big is the SF 01 Compute Board?
The SF 01 Compute Board measures 128 × 128 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the SF 01 Compute Board?
332 components, from 74 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 SF 01 Compute Board design files?
From the sandgum/Triangulate-SF_01-Speaker-Frame 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 SF 01 Compute Board design in my own project?
The repository has no license, so all rights stay with sandgum. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the SF 01 Compute Board 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.
