SRWF-1100A module is used to supply enable design for customers, the module does not take with MCU by itself , it only offer customers user interface for operation. Condition: Power Supply Work voltage of module is 1.8V-3.6V, recommending to use 2.8V. If the working voltage of MCU is higher than module`s, between each working port and MCU I/O port must be linked with resistance in series to separate them, and the range of supplying voltage between them is not too far. (recommending the same power supply to offer electricity) RE/TE Control instruction: RE/TE is used to control power of data receiving in expansion and transmission
