Hi Prince,

Sorry for the delay. I could not find a spec for the maximum current. However, looking at the schematics it seems like the 5V Boost regulator, XC9130.

The regulator is rated 500mA, and most of it is available to you. Usually less than 10mA and rarely up to 30mA is consumed by nRF52840.

There is also an option to supply the board externally.

Best regards,

Håkon
