CLRM701
Mifare & ICODE contactless reader module
5.2 Power supply
The controller board supports various power supply sources, which have to provide a
regulated 5V DC voltage. Figure 3 shows the possible power supply on the CLRM701.
In the default configuration, the PEGODA reader is a USB bus powered reader. No
external power supply has to be connected.
Remark: In order to fulfil the USB specification version 1.1, the reader module behaves
like a low power device after power on. Having sent an ACTIVATE command, the
PEGODA is activated and the reader module switches to an idle state resulting in an
increased power consumption. Only one power source must be connected to the board.
5.3 Boot jumper and serial I/O
The PEGODA reader offers a boot jumper to enable a firmware update as well as several
serial I/O pins to fulfil different user and application specific requirements. Figure 4 shows
the location of the boot jumper and the serial I/O pins.
