1.4 Safety

The SBC-C20 board uses only extremely-low voltages.

While handling the board, please use extreme caution to avoid any kind of risk or damages to electronic components.

1.5 Electrostatic discharges

The SBC-C20 board, like any other electronic product, is an electrostatic sensitive device: high voltages caused by static electricity could damage some or all the

devices and/or components on-board.

1.6 RoHS compliance

The SBC-C20 board is designed using RoHS compliant components and is manufactured on a lead-free production line. It is therefore fully RoHS compliant.

Always switch the power off, and unplug the power supply unit, before handling the board and/or connecting cables or other boards.

Avoid using metallic components - like paper clips, screws and similar - near the board when connected to a power supply, to avoid

short circuits due to unwanted contacts with other board components.

If the board has become wet, never connect it to any external power supply unit or battery.

Check carefully that all cables are correctly connected and that they are not damaged.

Whenever handling an SBC-C20 board, ground yourself through an anti-static wrist strap. Placement of the board on an anti-static

surface is also highly recommended.
