What's included

These are delivered in a sealed ESD bag, with pinheaders included.

Note that I'm merely reselling these AS-IS to make it a one-stop-shop for building your keyboard.

You can likely find them cheaper on AliExpress or similar if you are willing to order from various sources. I'm merely covering my expenses, shipping/taxes etc, with no actual measurable profit reselling these.

Normal handling time is 3-5 working days (Predominantly done on weekends). Build items usually take 1-2 weeks. All packages are represented to the courier/customs at their true value, and all responsibility for import fees and taxes resulting there of lies with the buyer.

All items are sold with a 24-month limited warranty, as per (2011/83/EU). Shipping of items returned for repair is solely the responsibility of the buyer. (This includes taxes and/or customs fees from incorrect/incomplete documentation.)

The SE "Act on Distance Contracts and Off-Premises Contracts" (SFS 2005:59) & The EU "The Distance Selling Directive" (97/7/EC) allow returns initiated within 14 days of receiving the item. Shipping of returned items is solely the responsibility of the buyer.

(Please note that in the case of kits that are mainly sold here, any warranty no longer applies once you start soldering/building the kit, as it is then no longer in its original condition, and you have at that point explicitly accepted the purchase contract! Please test components and initiate a warranty claim BEFORE you solder them!)
