The PQFP package is the most cost-effective.The transmission is conducted over 1 channels.As for packaging, Bulk is chosen.For a long-term satisfactory performance, it is necessary not to exceed the operating temperature of -40°C.It is important to keep the operating temperature below 85°C to ensure a long working period.Keeping the supply voltage below 5.5V will ensure reliability.When the voltage of the supply exceeds 3V, the system will be more reliable.UART operates at a high efficiency due to the voltage supply of 5V.
