Differences between libraries names: PCB Design of nRF52832https://devzone.nordicsemi.com/f/nordic-q-a/18027/differences-between-libraries-names-pcb-design-of-nrf52832I am intended to integrate the Nordic SoC nRF52832 in our PCB to generate a PWM. However, I could not understand the difference between the following: topicSchematic QFAA and QFAB QFN48 with internal LDO setup topicSchematic QFAA and QFAB QFN48en-USTelligent Community 13Mon, 28 Nov 2016 21:35:58 GMTRE: Differences between libraries names: PCB Design of nRF52832https://devzone.nordicsemi.com/thread/69489?ContentTypeID=1Mon, 28 Nov 2016 21:35:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0062ed7a-aee5-4dd7-932f-50f77115fec9RK<p>QFAA vs WLCPS is the chip packaging, Quad Flat No lead or a chip-scale package, you can look the package details up in the reference manual.</p> <p>The LDO vs DC/DC is what kind of power supply is used, a simple but slightly wasteful LDO or a more efficient DC/DC requiring a few more components.</p> <p>The NFC fairly directly says whether there is circuitry for an external NFC antenna.</p> <p>Pretty descriptive really.</p><div style="clear:both;"></div>
