The supercapacitor can be charged when the EVM is plugged into the PC or when the board is externally powered. During charging, set J4 to the “Charge” setting, this adds in a current limiting resistor for charging.
To charge the supercap, power must be coming from the eZ-FET debug probe, external power through J5, or a BoosterPack module powering through J1. Allow two to three minutes for the supercap to charge (time may vary depending on initial charge of the supercap and your power source) to full VCC.
