Hardware instructions

Precautions before use

  1. Make sure the power supply voltage must be 4.5-5.5V. If the power supply exceeds or falls below this range, the machine cannot work normally. If the power supply voltage is too high, the module screen will be damaged.
  2. Determine whether the serial port level is RS232 or TTL or RS485, and choose according to the requirements in conjunction with the fourth point.
  3. Pay attention to the interface definition instructions of the power interface socket, and do not connect it wrongly.

Serial output mode selection

As illustrated
0R resistance is TTL, 0R is not RS232.

The module screen corresponds to the external device interface diagram
