• Power supply for P5V_REG_IN supply
J3 2x8-pin Arduino power
header provides 5 V
input power supply
through pin 16
P5V_DC_IN One of the sources for P5V_REG_IN
J26 CP2102 Micro-AB USB
connector providing 5 V
power supply
P5V_USB2 One of the sources for P5V_REG_IN
- From P5V_REG_IN P5V • Power supply for voltage regulator, LD1117 (U2)
• 5 V power supply for pin 12 of 2x8-pin Arduino
power header (J3)
Table 9. 5 V power sources
[1] P5V0_OSDA_OUT is only available from P5V0_OSDA when USB cable is connected to J12, and a correct OpenSDA firmware has been programmed
into MK26FN2M0VMI18 (A correct OpenSDA firmware is programmed into MK26FN2M0VMI18 during MC56F80000-EVK manufacturing).
The following figure shows the power switch circuit diagram.
