DemoKit-LF3 User’s Manual
Table 3. Connector J2 inputs
2.6 J4: I
Connector J4 (not assembled) can be used to measure the microcontroller’s current consumption. To use
this mode, open the V8 soldering bridge.
2.7 J5: external power supply input
Connector J5 (not assembled) enables you to apply an external power supply to the DemoKit-LF3 board
without an active USB connection.
Table 4. Connector J3 inputs
2.8 Y1: external main oscillator
The microcontroller’s clock generator can be configured to work with an external oscillator connected to
the X1 and X2 pins. For this mode, you must equip the board’s Y1 pad with a corresponding oscillator.
Refer to the microcontroller user’s manual for a description of how to configure the clock generator.
2.9 OCD1: QB-MINI2 connector
Connector OCD1 (not assembled) enables you to connect the QB-MINI2 on-chip debugging emulator
(available separately) to the DemoKit-LF3 board to use the microcontroller’s on-chip debugging function.
