https://devzone.nordicsemi.com/f/nordic-q-a/112373/nrf52-data-rateWith the change from nRF51 to nRF52, the data rate became a minimum of 1 Mbps. Nordic proprietary radio mode, nRF51 250 Kbps. nRF52 1 Mbps, What is the difference in communication range and current consumption?en-USTelligent Community 13Mon, 24 Jun 2024 11:58:03 GMThttps://devzone.nordicsemi.com/thread/490265?ContentTypeID=1Mon, 24 Jun 2024 11:58:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5b35df19-26d3-4dc9-82db-896042364127SwRa<p>Hello,</p> <p>The nRF51 is very old product from Nordic and there are several Devzone tickets comparing nRF51 and nRF52 series like these:&nbsp;&nbsp;<a href="https://devzone.nordicsemi.com/f/nordic-q-a/21889/nrf52-and-nrf51-beacon-range">NRF52 and NRF51 (Beacon) Range</a>&nbsp; For the power consumption, you can use the online power profiler to check the consumption on thenRF52 and nRf53 series:&nbsp;<a href="https://devzone.nordicsemi.com/power/w/opp">https://devzone.nordicsemi.com/power/w/opp</a>.&nbsp;There are no similar tools for the nRF51 series, but the nRF52 series has better power consumption.. The nRF51 is not recommended for new BLE designs anymore.</p> <p><span>Range will depend on antenna and environment, and we can&#39;t really provide any value here as everyone test it differently (it can be as short as 10m or as long as 100m). You should get a kit and try it out in your environment to know how it performs.</span>&nbsp;&nbsp;</p> <p>Regards,</p> <p>Swathy</p><div style="clear:both;"></div>
