Hi Gilbert,
Good to read your are positive about Zymkey !
The ProtoKit5 is for prototyping your application, with some tamper switches on board to illustrate how you might connect a tamper circuit in your application.
It is not intended as a ‘bullet proof’ tamper proof enclosure - which can be difficult and costly to achieve, especially as a generic solution. Unfortunately one size does not fit all !
For some ideas on how other customers have integrated tamper detect circuits, check out here >
The custom shield is one such example (for the smaller ProtoKit4), but not sold as a standard product.
Zymbit does supply custom engineered tamper circuits and tamper proof enclosures for OEM applications. If you can send us some information on what level of physical security you are hoping to achieve, also what your volume and cost targets are then we can respond with some ideas and solutions. Please send your information, and contact details here > contact zymbit
