All prizes not claimed within 6 months will be put back into the prize pool. Please note that some items may require payment of customs charges when they arrive in destination countries.

Also, note that if something has a battery in it, it pretty much always means stress with sending them. These rules seem arbitrary and subject to constant change, so where possible, we'll ship things without the batteries and let you find one locally.

Electromaker contests are separate from the Electromaker store (I literally go to the post office to send prizes) so beyond giving tracking details there isn't a lot we can do if something goes missing.

It's been almost exactly 2 years since I won Electromaker's giveaway of an nRF5340 Audio DK, and honestly it's been both a blessing and a curse. Using it at all required learning Zephyr, and since I simply could not let the hardware just sit on a shelf, I dove headfirst down the rabbit hole.

Every single step has been insanely challenging; the CMake toolchain and VSCode plugins, the West-based SDK, the bewildering Devicetree abstractions and bottomless Kconfig options, not to mention the RTOS intricacies of multithreading semaphores and mutexes.

Zephyr is, without a doubt, the most complicated system I've ever studied, and I've been a college professor teaching live digital audio engineering for a decade! It is an incredibly powerful tool, and one arguably worth learning, but as someone who's been programming since the Apple 2, it is a difficult bootstrap even for the dedicated.

"enjoyed", not much, and then a very short breadboard os segment, just saying, what do i use the m2 hat for, drumroll : os and storage,
tip : get the low cooling fan kit, embedded case fan is obsolete with the m2 hat.
