EVK

The EVK is provided to help users to test and evaluate the EM1395-LD, which contains beeper & beeper

driver circuit, LED & LED driver circuit, trigger & reset buttons, TTL-232 to RS-232 converter & TTL-232

to USB converter, RS-232 & USB interfaces, etc. The EM1395-LD can be connected to the EVK via a

12-pin FFC cable type 1 (contacts on the same side). Either USB or RS-232 connection can be used

when connecting the EVK to a host device.
