T dsp desktop pro: common questions
What microcontroller does the T dsp desktop pro use?
The T dsp desktop pro is built around the ESP32-DevKitC - DEVKIT, from the ESP32 family.
How big is the T dsp desktop pro PCB?
The T dsp desktop pro measures 120 × 100 mm, has 8 copper layers and is 1.6 mm thick.
How many components are on the T dsp desktop pro?
135 components, from 51 distinct parts. The full bill of materials is listed on this page.
Where can I download the T dsp desktop pro design files?
From the t-dsp/t-dsp_desktop_pro repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the T dsp desktop pro design in my own project?
It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.
Can I test firmware for the T dsp desktop pro 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.
