General safety instructions and information.
- The usual precautionary measures when handling electrical voltages have to be observed.
- Electrostatic discharge (ESD) can instantly destroy electronics if you do not take appropriate precautions.
- Inductive and capacitive voltage spikes can instantly and unexpectedly destroy electronics when you apply power, even if you are careful about electrostatic discharge (ESD).

- Fully charged batteries can have a significantly higher voltage than their nominal voltage value.
- Wall wart power adapters are often unregulated, so that a 9V adapter might initially output 12V and with the voltage dropping as the load increases.
- Breadboards and jumper wires are not appropriate for carrying high currents.
- Connectors (pin headers) only have a contact when they are soldered to the PCB.
- Mechanical damage or strong thermal stress can cause internal short circuits, which can lead to high currents and thus to high heating.
- Lithium is a highly reactive metal. Burning batteries with lithium are not allowed to extinguished with water, please use for example sand.
- Damaged batteries have to be disposed of in appropriate safety containers immediately.
- Do not leave rechargeable batteries unattended while charging.
- The usual protection and precautionary measures when handling laser radiation and high power light sources have to be observed.
- We strongly recommend wearing appropriate safety glasses when working with laser or high power light sources.
- Be careful when handling strong magnets (e.g. made of neodymium) to prevent pinching and splintering due to their brittleness.
- Magnets create a far-reaching and strong magnetic field. Among other things, they can damage or harm computers, memory disks, credit cards or pacemakers.
- The usual protection and precautionary measures when handling chemicals have to be observed.
- Further necessary preventatives can be taken from the product label and packaging and the safety data sheet.
