Programming the nRF52832 through serial, without the development board?

[naoki77]

Is there another IC I need to integrate into my board to allow the chip to be programmed through USB? Also, is the same true for programming OTA? I understand that I will need a programmer such as the J-Link BASE to provide the chip with a bootloader once the chip comes fresh from the factory.

If you want to use USB then you need a chip which supports USB as the nRF52 doesn't, so you'll need a USB/serial chip. OTA you need nothing after the initial programming as the transport is done over the air.
