ESP32 Master V2: common questions
What microcontroller does the ESP32 Master V2 use?
The ESP32 Master V2 is built around the ESP32-DEVKITC-32E, from the ESP32 family.
How big is the ESP32 Master V2 PCB?
The ESP32 Master V2 measures 105 × 90 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ESP32 Master V2?
99 components, from 48 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 ESP32 Master V2 design files?
From the tetra-aero/LTC6811_ESP32 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 ESP32 Master V2 design in my own project?
Yes, under the terms of its GPL-3.0 license, which tetra-aero chose for the repository.
Can I test firmware for the ESP32 Master V2 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.
