Bare die cast in resin - MPW4

A souvenir from the 4th open source MPW shuttle run.

The program was sponsored by Google, facilitated by Efabless and manufactured by Skywater on their 130 nanometer process.

50 dies were received and were set in a 20mm resin cube.

Note that due to being cast in resin this die cannot be used.
