Timing Sequence

Power Up and Power Down Timing Sequence

1. A represents reset time, about 200ms.
2. B represents time for starting the engine. The total is A plus B, about 3200ms. The engine can receive serial commands or
USB communication immediately when it is powered on.
3. C is the power-down time, indicating all the voltages' drop time in the module, that is, the communication is stopped and the
level is low. In order to ensure the voltage is fully down and the level of each interface is low, at least 700ms interval is required
to start the engine again.
