6.2、power supply requirements
(1) It is recommended to use DC regulator power supply to supply power to the module. The
power ripple factor is as small as possible and the module needs to be grounded reliably. Please
note that the correct connection between the positive and negative poles of the power supply,
such as reverse connection may cause permanent damage to the module.
(2) Check the power supply to ensure that between the recommended supply voltage, if the
maximum value is exceeded, the module will be permanently damaged; check the power supply
stability, the voltage should not fluctuate significantly and frequently;
(3) Recommend 3.3V voltage, LDO power supply is recommended; if using DC-DC, ripple
control is recommended within 30mV.The DC-DC power supply circuit suggests reserving the
position of the dynamic response capacitance to optimize the output ripple when the load varies
greatly.
6.3、UART Communication
UART communication between module and master MCU through serial port supports full
duplex transmission and reception of TX and RX.
