https://devzone.nordicsemi.com/f/nordic-q-a/117159/choosing-among-nrf52840-nrf5340-and-nrf54l15Hi i am currently, doing development on nrf52840. where I have 48 number of GPIO&#39;s available. for my application, I have peripherals like Touch screen RGB display, UART based Modem, 4x4 keypad matrix. In short, I have so much to configure with my boarden-USTelligent Community 13Tue, 10 Dec 2024 14:38:15 GMThttps://devzone.nordicsemi.com/thread/514301?ContentTypeID=1Tue, 10 Dec 2024 14:38:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7bef0e4e-1868-42f1-afde-477274cd36dcEdvin<p>Hello,</p> <p>Both the nRF52840 and nRF5340 devices have 48 GPIOs, where the pins are very flexible (meaning you can use all GPIOs for almost all peripherals). There are some limitations, such as NFC being locked to two pins, and if you want to use an external LFXTAL, that takes two GPIOS (P0.00 and P0.01).&nbsp;</p> <p>The nRF54l15 has 32 GPIOs, and it has some more restrictions on what pins that can be used for what.
