PRODUCT TESTING SALE!!
Warning!!! this product is in the testing phase. The product description is a work in progress.
when I have tested the product myself and finished untangling the product description from the supplier the product testing price drop will end and the regular price will apply.
due to shortage of 2209 drivers, the ender mini board with integrated drivers has not been listed here. this is a listing for the ender 3 skr board with dip plugs so you can use whatever drivers you like. It comes with 2208 drivers installed. and should be correctly preconfigured out of the box. The description below may contain errors and information on other unrelated products as is typical with Chinese wholesale websites. When my sample package arrives I will confirm everything in the listing is correct and in working order and the introductory sale will end. I am only covering costs with this introductory price so jump in now if you want to be a beta tester, or wait for the price rise if you want to know it will just work out of the box.
