Pine64 (Pine Store Sdn Bhd) Pinecil V2

D1 Local Only — Speaks only to hardware you control.

The unplug test

There is nothing to unplug from. The Pinecil is a USB-C/barrel-jack powered soldering iron, configured and used entirely from its own on-device menu and OLED screen; the only thing on the network is your own room, if you choose to pair the BLE radio to a phone at all. Every setting -- temperature, sleep behavior, power source negotiation -- lives in the iron itself and in the open-source IronOS firmware you flash onto it over USB, not in any account.

Why this tier: The Pinecil V2's Bouffalo BL706 chip includes Bluetooth Low Energy hardware, and IronOS -- the open-source firmware it ships with as the stock, out-of-box experience -- lists BLE as a supported feature on Pinecil V2 in its current stable release. PINE64 operates no account system, app store, or cloud service of any kind for the iron: BLE is used only for local, in-room communication with a phone or PC, so the radio's presence puts this at D1 rather than D0, with no vendor cloud in the picture to make it D2.

Class A is primary (manual, FCC filing, teardown). Class B is corroborated community reporting. Class C is never sufficient alone.
