This is to prevent you - from causing any ESD damage. The surface that you place components on should also be earthed/grounded. - (for this, I used a shielded ESD bag with a wire, copper exposed, attached from the bag to the exposed metal - part on a radiator, which was earthed - not professional, but it should work. see <a href="images/x200/mat.jpg">images/x200/mat.jpg</a>). - Most people ignore this advice and don't ground/earth themselves, at their own risk. You should also store the BBB - in a shielded anti-static bag when you are finished with it. - (the principles above apply to any computer components, since they are extremely sensitive te ESD). - </p> - <p> - These instructions may or may not work for you.
