OpenSpritzer-V2: common questions
What microcontroller does the OpenSpritzer-V2 use?
The OpenSpritzer-V2 is built around the ESP32-DEVKITC-32D, from the ESP32 family.
How big is the OpenSpritzer-V2 PCB?
The OpenSpritzer-V2 measures 200 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the OpenSpritzer-V2?
75 components, from 51 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 OpenSpritzer-V2 design files?
From the MaximeZimmermann/OpenSpritzer-V2 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 OpenSpritzer-V2 design in my own project?
Yes, under the terms of its GPL-3.0 license, which MaximeZimmermann chose for the repository.
Can I test firmware for the OpenSpritzer-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.
