REB-4315 Operational Manual 5 Reference schematic: For example: Note: (1) Ground Planes: These pin(8、18、20、21、22) should be connect to ground. (2) Serial Interface: (Ⅰ)The TX pin is the serial output data. (Ⅲ)The RX pin is the serial input data.< UART data receive (RX)> (3) RF_IN: Connecting to the antenna has to be routed on the PCB. The transmission line must to be control impedance from RF_IN pin to the antenna or antenna connector of your choice.
REB-4315 Operational Manual Input pulse is required to start the system, and switch the operation mode to full-power mode or Hibernate mode. (7) Wakeup： Wakeup output indicate the chip states, when chip is working the output is high level. Wakeup output can control or enable the external regulator.(Ex. To control external antenna power) (8) Boot Set this pin to high for programming flash. Normal operation mode it is set to low voltage.
