Summary
The ID-20LF series contactless card Read/Write module is based on 3 types 125khz read
and write chip. They come with the choice of internal antenna (optional) or external antennaand are suitable and for embedded applications and general Electronic Devices. The
ID-20LF-EM series are user friendly and can be controlled by command from a UART
(serial port). Functions are selected by a Pin jumper allowing full control of all functions.
Characteristic
. 2 options antenna setting: internal antenna (optional) or external antenna (standard)
