Open-hardware for electrostatic discharge testing (O-ESD)
O-ESD is open-hardware project for (pre-compliance) ESD immunity testing in accordance with IEC/EN 61000‑4‑2 standard. It is a stand-alone battery-powered portable device that can produce low-energy voltage pulses in the range from –15 kV to 15 kV. All electronic devices must be immune to a certain level of ESD, as ESD happens everyday between humans and electronic devices.
O-ESD is released under CERN Open Hardware License Version 2 – Strongly Reciprocal.
The current release is version 1.0.
Electrostatic discharge can irreparably damage electronic devices. Use O-ESD with caution!
