COLDCARD Q - Bitcoin only hardware wallet

The COLDCARD Q by Coinkite is the premium Bitcoin-only hardware wallet for ultimate air-gapped security – featuring a full QWERTY keyboard, a large 3.2" LCD screen (320x240 pixels), and an integrated QR scanner. It replaces the Mk4 with the same dual-secure-element setup (two multi-vendor chips like the ATECC608A), trick PINs for duress scenarios, and open-source firmware – minimizing attack surfaces for pure BTC sovereignty.

Unique features: Battery operation with 3 AAA batteries (or USB-C, 93 g without batteries, 120 x 75 x 22 mm), two push-pull microSD slots for PSBT transactions, NFC communication (disableable by cutting the circuit trace), and an LED-illuminated QR scanner with serial isolation. Easy BIP-39 passphrase entry via keyboard, flashlight function, internal SD card storage, and USB virtual disk mode. Compatible with Sparrow, Nunchuk, and Specter for multisig and air-gapped signing – no Bluetooth/WiFi, purely offline.
