Note: Module UART high level is 1.8V, please use external level shifter if connect to 2.8V or 3.3V IO interface. 

When you design: 

Level shift from 1.8V to 3.3V, SN74LVC2G07 is recommended. 

When UART1 communicating with PC, first translates from 1.8V to 3.3V, and then uses SP3238 to translate. 

When UART2 communicating with PC, first translates from 1.8V to 3.3V, and then uses SPIEX3232EEA to 
translate level. Notice the signal direction when translate level.
