3. CONNECTORS PIN CONFIGURATION

ZB-UPS01/ZB-UPH01 uses Silicon-Lab C8051F340 as MCU. It is an 8051 base MCU and

reserves 10 GPIO pins for external controlling by application. Each pin can be a general I/O pin

and programmed it by user directly. Furthermore, most of these pins can be used as special purpose

function. Thereof TX, RX pins can be programmed as UART for data communication. For

example, user is easy to connect these pins with RS485 transceivers such as 75176, MAX485.
