Differences between libraries names: PCB Design of nRF52832

[Badred]

I 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 QFN48 with DC/DC regulator setup

topicSchematic QFAA and QFAB QFN48 with DC/DC regulator and NFC setup

topicSchematic CIAA WLCSP with internal LDO setup

topicSchematic CIAA WLCSP with DC/DC regulator setup

topicSchematic CIAA WLCSP with DC/DC regulator and NFC setup

Can you please explain to me what each one means? Thank you

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.

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.

The NFC fairly directly says whether there is circuitry for an external NFC antenna.

Pretty descriptive really.
