  • 2026-04-23 — Historical result. Tim Ansell reported about 80% success in Tiny Tapeout CoB testing, where all wire bonds worked. This was the basis for starting the first 20 bonds of 1x1 designs. (archive message; Discord)
  • 2026-04-26 — Historical result and corrective action. The first shipped 1x1 batch had about 20% packaged-die test failures, thought likely to be bond-wire lift. Its PCB also left PWR_AUX_1 disconnected from the header. The message planned process changes. (archive message; Discord)

These figures describe an early batch. They are obsolete as an undated current-yield claim.

Historical pricing

The archive describes the old CoB price in two compatible forms: an $8,500 total option in October 2025, and a $1,500 add-on to a $7,000 slot in November 2025. Both are campaign-era pricing and must not be shown as current. (archive message; Discord) (archive message; Discord)
