Fully Built 2.8" CYD (Duggie Build)

This is the real deal. A complete, ready-to-run handheld CYD for your favorite firmware — hand-wired by Duggie. No soldering, no sourcing, no guessing.

One of one. Built by hand. Never another exactly like it.

The build:

• 2.8" CYD in the Duggie Edition PLA Pro Carbon Fiber case
• 1000mAh flat lithium cell — internal, rechargeable
• Full power stack: charging board, boost, buck, boot switch, power switch — all wired and tested

Radios on board (all quick-detach):

• NRF24L01 — 2.4GHz transceiver
• CC1101 — Sub-GHz transceiver
• PN532 — NFC / RFID read & write
• Bolton 2.4GHz antenna
• Tri-band Sub-GHz antenna for the CC1101
• GPS via ATGM336 with a ceramic GPS antenna built into the case — no external antenna to snap off
• Upgraded onboard antenna swap to SMA for longer reach

Upgraded antennas — free upgrade for first 10:

• Triband Sub-GHz
• Bolton 2.4GHz

Every radio module is wired on quick-detach connectors — if one ever fails, swap it in seconds. No desoldering, no rework, no downtime.

Extras:

• Integrated stylus holder (with stylus)
• 8GB SD card included — ready for logs, captures, and configs
• USB-C charging

Quality: Every unit is hand-wired by Duggie personally and bench-tested for a minimum of 2 days before shipping. Radios verified, GPS lock confirmed, battery cycled, touchscreen calibrated. If it leaves my bench, it works.

This does not arrive in a functional state — you must flash firmware onto the device.
