VDD_36 is for operating of PR9000 RFID reader chipset which current consumption is about 150mA. VDDPA_36 is for operating of power amp which current consumption is 350mA typically. Additionally, decoupling capacitors should be placed as close as possible these pins. The decoupling capacitors should be placed in the same layer as the module, to avoid any additional parasitic inductance caused by vias. 3.2 Hardware Mode Control PRM90U10A provides normal mode and shut down mode. The mode can control by SHDNb(Pin 24). Normal mode should be controlled by SHDN pin to open which can activate the module. Otherwise, If SHDNb pin contact to ground, supplied power of the module is shut down internally. In shut down mode, all GPIO ports and UART ports should not input any signal and positive voltage. 3.3 UART The serial interface assigned to two pins. RXD1(Pin 13) is for receiving command from host and TXD1(Pin 14) is for transmitting response to host. Pin connection is shown as below figure.
