Remarks:  All IO high levels are 3.3V @ 5V power. At a data rate of 2 MHz, the power can be set as high as level 3. However, when operating at 250 kHz or 1 MHz, the power level should be set to 1; otherwise, communication data loss may occur.  The antenna negative pin 'PIN13' cannot be connected to the system ground of the PCB! If connected, it will affect the receiving sensitivity of the module. Therefore, when using a wire antenna or a spring antenna, the PIN13 should be left floating. Refer to the Layout as shown below:
