https://devzone.nordicsemi.com/f/nordic-q-a/69884/chip-selection-issue-nrf52840Hello We are planning to build a product based on nrf52840 our programming part is almost done we used nrf52840Dk board , now we are order SoCs and other peripherals , but there is some problem we find NRF52840-QIAA-R and NRF52840-QIAA-R7 , in Digikeyen-USTelligent Community 13Mon, 28 Dec 2020 15:29:15 GMThttps://devzone.nordicsemi.com/thread/286758?ContentTypeID=1Mon, 28 Dec 2020 15:29:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4c9e3c2c-8ee7-4f0f-9b00-9e10ccd21553Vidar Berg<p>Hello,</p> <p>They are both the same chip (<span><a title="SoC revisions and variants" href="https://infocenter.nordicsemi.com/topic/comp_matrix_nrf52840/COMP/nrf52840/nRF52840_ic_revision_overview.html?cp=4_0_3_0">SoC revisions and variants</a></span>). The difference is the container type they come in. &quot;R7&quot; means that the ICs come in a 7&quot; reel and &quot;R&quot; that they come in a 13&quot; reel.
