OpenShock: common questions
What microcontroller does the OpenShock use?
The OpenShock is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the OpenShock PCB?
The OpenShock measures 45.3 × 75.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the OpenShock?
34 components, from 18 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 OpenShock design files?
From the OpenShock/Hardware 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 OpenShock design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which OpenShock chose for the repository.
Can I test firmware for the OpenShock 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.
