Table 4-3. J202 Power Header
J202 pin Signal Description
1 NC
2 VCC_TARGET The power source selected for the target (select by J301)
3 RESET_SENSE This is a RESET signal monitored by the mEDBG. If pulled low the
target RESET line will be pulled low by the mEDBG. The ATmega32U4
internal pull-up is enabled. This signal is not available during debugging.
4 VCC_P3V3 The 3.3V regulator output
5 VCC_P5V0 The selected power source (VIN or VBUS selected by J300)
