Production/Stock Status

Hello snickerdoodlers,

A brief update:

  • 50 more snickerdoodles are on track to be delivered to Crowd Supply later this week, which accounts for the last of the ‘original’ snickerdoodle pre-orders.
  • Crowd Supply is currently shipping out the last of the snickerdoodle one pre-orders, and will soon have a (small) stock of snickerdoodle ones – connectors up and down – available for order.
  • 100 more snickerdoodle blacks (including the last of the 'connectors up' preorders) are scheduled to be delivered to Crowd Supply by the end of June.
  • piSmasher is going to fab the last week of May; if all goes according to plan, we should (finally) be shipping production units by mid July.
  • There will be more announcements regarding the final piSmasher details in the coming weeks/months; to correct a previous update, there will only be one piSmasher version.
  • The new krtkl website will be live by the end of June – if you have any projects you’d like spotlighted on the new site, please let us know.
  • Mouser and Digi-Key have limited stock of snickerdoodle Prime LEs and breakyBreakys.
  • If you’re still awaiting your order, don’t forget to update your Crowd Supply account if your shipping/delivery details have changed.

If you have any questions about your order or anything else, please email us at

Kind regards,

the krtkl crew
