3. CONNECTORS PIN CONFIGURATION
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.
