Welcome to the dev site. Use this site at your own risk. There are very definitely ways your stuff is insecure on this site! We might delete things when making structural changes! File uploads in the store and forum have no form of protection! Don't put anything on this site you wouldn't like shared with the world.
dev shop is where we experiment with new stuff before it goes live at Seeed Studio and our distributors. Feel free to check it out, but we ABSOLUTLY CANNOT guarantee the level of service you'd get at Seeed Studio and our distributors. We're just grabbing this stuff from Huaqiangbei as you buy it, if it is popular we'll move it to our normal retail channels.
