Cautions & Warnings:

Development boards do not necessarily have the same ESD protection as those afforded in an enclosed commercial product and are not necessarily EMC compliant either. Please ensure you are familiar with ESD handling precautions when working with development boards. 

Please be aware of the type and quality of board you are purchasing. These boards are not recommended for use in a commercial or industrial setting but are great for use in a developmental or electronics maker/hacking environment. Please note that due to the complexity of issues related to development work, these boards are not provided with any warranty or technical support and no warranty is provided as to the fit-for-purpose for customer applications. However, we will always try and help with customer support enquiries and welcome feedback.
