5.1 Power The EK-RA2L1 kit is designed for +5 V operation. An on-board Low Dropout Regulator (LDO) is used to convert the 5 V supply to a 3.3 V supply. The 3.3 V supply is used to power the RA MCU and other peripheral features. -
Page 18: Power Supply Options
5.1.3 Power-up Behavior When powered, the white LED near the center of the board (the “dash” in the EK-RA2L1 name) will light up. For more details on initial power up behavior, see the EK-RA2L1 Quick Start Guide. -
Page 19: Debug And Trace
J10-5 Ground A yellow indicator, LED5, shows the visual status of the debug interface. When the EK-RA2L1 board is powered on, and LED5 is blinking, it indicates that the S124 Debug MCU is not connected to a programming host. When LED5 is on solid, it indicates that the S124 Debug MCU is connected to a programming interface. -
Page 20: Debug In
Debug Connector at J13 supports JTAG and SWD. Either of these connectors may be used for external debug of the target RA MCU. To configure the EK-RA2L1 board to use the Debug In mode, configure the jumpers using the following table. -

6.1 Breakout Pin Headers The EK-RA2L1 board pin headers, J1, J2, J3 and J4, provide access to all RA MCU interface signals, and to voltages for all RA MCU power ports. Each header pin is labeled with the voltage or port connected to that pin. -
Page 31: Mcu Current Measurement
Included in the Native Pin Access area is a current measurement resistor and test points to measure the MCU core power current. The EK-RA2L1 board provides a precision 5 mΩ resistor (Vishay, part number WSLP08055L000FEA18) for current measurement of the main 3.3 V MCU power. Measure the voltage drop across these resistors and use Ohm’s Law to calculate the current. -
