    Cypress Technical Support. Kit Compatibility This kit contains an expansion board and requires other Cypress kits to use it. It is designed to add CAN and LIN capabilities to the CY8CKIT-001 PSoC Development Kit (DVK). This DVK supports PSoC 1, PSoC 3, and PSoC 5 families. However, it may be necessary to obtain or purchase additional processor modules for the CY8CKIT-001 to develop applications for a particular PSoC device family.
