nRF52810 Hardware version issuehttps://devzone.nordicsemi.com/f/nordic-q-a/62969/nrf52810-hardware-version-issueHi, I want to know what is the different between QFAAB0 and QFAAD0. The IO of QFAAD0 version seems to be broken down easily.Maximum 4mA current flows into IO.en-USTelligent Community 13Mon, 29 Jun 2020 02:18:29 GMTRE: nRF52810 Hardware version issuehttps://devzone.nordicsemi.com/thread/257259?ContentTypeID=1Mon, 29 Jun 2020 02:18:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6f6d6464-a67e-4855-969f-0bc460902fd6james<p>thanks.
