From the project
A Flipper Zero GPIO carrier for the common 8-pin CC1101 sub-GHz module, with a prototyping area and a breakout for the Flipper signals the radio does not use.

61.34 × 32.84 mm, two layers, hand-solderable throughout (0805 passives, SOT-23-6, SOD-123). ERC and DRC are clean; the only remaining DRC entries are silkscreen overlap warnings where a connector's own pin labels sit close to its pads.
