ABR200 Integration Manual
3.2 Power supply 5.0V
In case the ABR200 should be supplied with 5.0V directly, the modules on-board boost converter
is not used. The 5.0V have to be connected to the “5V-IN” pin of the reader. The pins “BAT-IN”
and “5V-OUT” are not used here and should be left open.
For switching on the ABR200s power supply, the “Enable” pin must be driven higher than 1.2V.
The diagram above shows the connection in case of providing 5.0VDC.
