ELISTARS: common questions
What microcontroller does the ELISTARS use?
The ELISTARS is built around the ESP32 Wroom, from the ESP32 family.
How big is the ELISTARS PCB?
The ELISTARS measures 102 × 86.3 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the ELISTARS?
281 components, from 125 distinct parts. The full bill of materials is listed on this page.
Where can I download the ELISTARS design files?
From the R-Mutura/ELISTARS repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the ELISTARS design in my own project?
The repository has no license, so all rights stay with R-Mutura. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ELISTARS 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.
