7 Reliability and Electrical
Characteristics
This chapter mainly describes the electrical characteristics of EVB interfaces, including: power supply
characteristics.
7.1. Power Supply Characteristics
The USB input voltage of the EVB is 5.0–5.1 V, and then it is converted by DCDC to 3.8 V power supply
for the module. The power supply requirements are shown in the following tables:
Table 6: Input Power Supply Range
Table 7: I/O Requirements
The typical value of VCC is 3.3 V.
