Notice and Warning 

 

Danger High Voltage!  

Electric  shock  possible  when  connecting  board  to  live  wire.  Board  should  be  handled  with  care  by  a 
professional. For safety, use of isolated test equipment with overvoltage and/or overcurrent protection 
is highly recommended. 
 

 

This product uses semiconductors that can be damaged by electrostatic discharge (ESD). When handling, 
care must be taken so that the devices are not damaged. Damage due to inappropriate handling is not 
covered by the warranty. 

The following precautions must be taken: 

-

 

Do not open the protective conductive packaging until you have read the following and are at 
an approved anti-static work station. 

-

 

Use a conductive wrist strap attached to a good earth ground. 

-

 

If working on a prototyping board, use a soldering iron or station that is marked as ESD-safe. 

-

 

Always disconnect the microcontroller from the prototyping board when it is being worked on. 

-

 

Always discharge yourself by touching a grounded bare metal surface or approved anti-static 
mat before picking up an ESD - sensitive electronic component. 

-

 

Use an approved anti-static mat to cover your work surface.
