Hi,

[quote user="StevenW807"]could I program multiple nRF52805 chips at the same time, please?[/quote]

No, only one at the time.

We do have a paper on production programming here https://infocenter.nordicsemi.com/topic/nwp_027/WP/nwp_027/intro.html?cp=17_7 , but you will have to program on at the time, or get more programmers. You can use some production programmers, but if your plan is to use the nrf25 DK then i am not aware of a solution that will speed things up.

Jonathan

Hi Jonathan, yes, debug out pin is an easier solution. If I use custom cable and connector for the debug out socket on nRF52 DK, could I program multiple nRF52805 chips at the same time, please?

What's the max number of chip that I can program at once, such as 10? Because I'm worry about the current and voltage limitations on the nRF52 DK.

Thanks!

Hi,

Using the debug out connector and a 10 pin ribbon cable is easier. Using some sort of pogo pin interface in a jig can be quite effective. It is also possible to program the chips before soldering them on the pcb, but for 3000 units this might not be a viable option, as that is often more expensive.
