https://devzone.nordicsemi.com/f/nordic-q-a/77506/selecting-remote-control-slave-ble-side-mcu-to-communicate-with-nrf52832-masterI am a systems engineer helping my team in the component selection phase of the project that involves BLE communication between our master side and a simple remote control. The MCU for master side is already selected (nRF52832 - 32 pins, 64kb RAM, 512kben-USTelligent Community 13Thu, 15 Jul 2021 13:59:07 GMThttps://devzone.nordicsemi.com/thread/320297?ContentTypeID=1Thu, 15 Jul 2021 13:59:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4b2efe3b-e796-4f1c-a738-b578e107b66eJared<p>Hi,</p> [quote user=""]<p>Since choosing the same MCU module would clearly be an overkill, what is a good practice for choosing a simpler / more cost effective MCU to pair with the master side? Do I select the exact same MCU with lower pins?</p> <p></p>[/quote] <p>It depends on your requirements. The nRF52810 is a less costly version of the nRF52832 and might be what you&#39;re looking for. I would suggest contacting our regional sales director for Canada for a further discussion regarding what products you should go for:</p> <p>Curt Waters</p> <p>curt.waters@nordicsemi.no</p> <p>regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
