EL6170 Pro Max Plus: common questions
What microcontroller does the EL6170 Pro Max Plus use?
The EL6170 Pro Max Plus is built around the ESP32-S3-WROOM-1U, from the ESP32 family.
How big is the EL6170 Pro Max Plus PCB?
The EL6170 Pro Max Plus measures 128 × 70.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the EL6170 Pro Max Plus?
159 components, from 106 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 EL6170 Pro Max Plus design files?
From the jsjsjsjsjsjsjson/EL6170_Pro_Max_Plus 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 EL6170 Pro Max Plus design in my own project?
The repository has no license, so all rights stay with jsjsjsjsjsjsjson. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the EL6170 Pro Max Plus 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.
