Electronic vapor provision system

(canceled)

A cartridge for a vapor provision system, comprising:

• a vaporizer for generating a vapor from a vapor precursor material for inhalation by a user, wherein the cartridge is detachably couplable to a power supply for supplying electrical power to the vaporizer across an electrical interface established between the cartridge and the power supply when the cartridge is coupled to the power supply for use;
• wherein the electrical interface is provided by contacts in the power supply and a contact board with contact pads in the cartridge, wherein the contacts and contact pads are arranged in cooperative alignment so that respective ones of the contacts are biased into contact with corresponding ones of contact pads when the cartridge is coupled to the power supply for use, wherein a component of the vapor provision system arranged to support the contact board in the cartridge comprises a resilient material.

A control unit for a vapor provision system comprising the control unit and a detachable cartridge comprising a vaporizer for generating a vapor from a vapor precursor material for inhalation by a user, the control unit comprising:

• a power supply for supplying electrical power to the vaporizer across an electrical interface established between the control unit and the cartridge when the cartridge is coupled to the control unit for use;
• wherein the electrical interface is provided by contacts the cartridge and a contact board with contact pads in the control unit, wherein the contacts and contact pads are arranged in cooperative alignment so that respective ones of the contacts are biased into contact with corresponding ones of contact pads when the cartridge is coupled to the control unit for use, wherein a component of the vapor provision system arranged to support the contact board in the control unit comprises a resilient material.
