JPL.mp3: common questions
What microcontroller does the JPL.mp3 use?
The JPL.mp3 is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the JPL.mp3 PCB?
The JPL.mp3 measures 40 × 100 mm, has 4 copper layers and is 1 mm thick.
How many components are on the JPL.mp3?
60 components, from 32 distinct parts. The full bill of materials is listed on this page.
Where can I download the JPL.mp3 design files?
From the jpetkauskas/JPL.mp3 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the JPL.mp3 design in my own project?
The repository has no license, so all rights stay with jpetkauskas. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the JPL.mp3 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.
