3.5 R Frost Case

Duggie Edition Frost (3.5" R CYD)

The official Duggie Edition case for the 3.5" Resistive CYD (Cheap Yellow Display). Designed to turn your CYD into a proper handheld tool — not just a dev board taped to a battery.

Printed in PLA Bone White for an ice-like, professional finish that looks as good as it holds up.

Comes fully populated with power components:

• Charging board
• Boost board
• Buck board
• Boot switch
• Power switch

.Just drop in your CYD and you're running. No sourcing parts, no guessing which boost converter plays nice with which charger — it's all in there and ready. Pre-tested, good to go.

Included hardware:

• 3mm black T8 screws

What you'll need to supply:

• 3.5" Resistive CYD board
• 1000mAh flat lithium cell (recommended — best fit for the case)
• Wire / your soldering iron
