299 The EV kit provides a USB-to-HART bridge chip, FTDI FT231. This bridge eliminates the requirement
300 for a physical RS-232 COM port. Instead, the IC’s HART access is through the Micro-USB type-B
306 The EV kit is powered by +5V that is made available through VBUS on the Micro-USB type-B
314 To accurately achieve the low-power current values, the EVkit needs to be configured
330 The EV kit provides a USB-to-UART bridge chip (the FTDI FT230XS-R). This bridge eliminates
331 the requirement for a physical RS-232 COM port. Instead, the IC’s UART access is through
332 the Micro USB type-B connector (CN1). The USB-to-UART bridge can be connected to the IC’s UART0
