Connector X5 – Power Supply Vcc
cVEND must be supplied by a regulated power supply of 5 V DC only. If switching power supplies
are used be sure that there is adequate filtering. Noise from the power supply can result in a reduc-
tion of the read/write range of the module. The cable length from the power supply should be as
short as possible, and should in any case not exceed 3 m.
