August 2025

  1. multiple boards and controllers support touch gestures, battery charging, and 5ghz WiFi
  2. our lead HW engineer also threw in a Qwiic connector, you knowjust to have it
  3. the circular area interfaces with a waterproof "puck" shaped charging connector, and several test points on the motherboard's bottom will let us build a QA jig for our warehouse
  4. prior to release we'll prototypes to your favorite creators for first-look reviews

September 2025

  1. we ordered 50x more prototypes with stronger magnets so devices can attach directly to a surface (e.g. refrigerator) without mounts
  2. dual band WiFi will be powered by the ESP32-C5 and we've benchmarked faster speeds + better range with custom modem firmware
  3. orders with the Battery Upgrade (or Clarity Kit) will now enjoy 10,000mAh versus the announced 7,000mAh variant
  4. our "charging puck" (name TBD) now has a universal connector for kickstands and other peripheral accessories that will debut in 2026
  5. the same firmware that runs all OG + BYOD devices has been extended and is already running my own X prototype, preview here

October 2025

  1. placed our first purchase order for several thousand screens
  2. submitted packaging designs, awaiting samples
  3. a small batch of touch (gesture) boards and charging pucks are being manufactured; if these behave as expected our board design will be complete and we can begin scaling production
