235 The EV kit is powered by +5V, which is made available through VBUS on the Micro USB type-B
239 Single- or Dual-Supply Operation
242 The EV kit is configured for single-supply operation. For dual-supply operation,
243 install a jumper on JP14 and connect an external supply to TP6 (VCORE_EXT) and ground.
252 Low-Power Mode Current Measurements
255 To accurately achieve the low-power current values, the EV kit must be configured such that
256 no outside influence (such as a pullup, external clock, or debugger connector) causes
267 The MAX32672 clocking is provided by an external 16MHz crystal (Y1).
269 External Voltage Reference
272 The external voltage reference input VREF for the ADC can be sourced externally by a high-precision
273 external reference source (the MAX6071). VREF (JP1) allows the external reference
280 The EV kit provides a USB-to-UART bridge chip (the FTDI FT230XS-R). This bridge eliminates
281 the requirement for a physical RS-232 COM port. Instead, the IC’s UART access is through
282 the Micro USB type-B connector (CN1). The USB-to-UART bridge can be connected to the IC’s UART0 or
290 The boot loader is activated by the boot-load-enable slide switch (SW2).
297 can be accessed through 0.1in-spaced headers J3 and J4.
324 SWD debug can be accessed through an Arm Cortex 10-pin connector (J5).
