The purpose of this article is to give a detailed account of the hardware specifications of Trezor Model T (show for Trezor One).
The casing, dimensions, and material
Trezor Model T is of approx 64 mm x 39 mm x 10 mm (2.52 in x 1.54 in x 0.39 in) in size and weights 16 g (0.56 oz). The case is made of a reinforced plastic providing great durability. The casing is put together using a method of ultrasonic welding.
Trezor Model T is a USB 2.0 and USB 3.0 compatible device. The device wields a Micro USB (type C) Receptacle port in the bottom part of the unit.
Other means of communication such as WiFi, Bluetooth, NFC, or even a fingerprint reader have been deliberately excluded in order to limit the possible attack surface.
ARM Cortex-M4 processor @ 168 Mhzwith custom software.
LCD touchscreen (240x240 pixels) used on Trezor T provides enough space to comfortably display the transaction details, requests for confirmation, warnings, or even simple images. The screen is an essential tool allowing the user to reliably check the legitimacy of entered data with no need to trust the host device(computer/phone).
The touchscreen gives the user the ultimate control of the device. The necessity of physical confirmation has been implemented to protect the accounts from a vast majority of remote attacks. Using the touchscreen is the only way to unlock the device, enter the PIN, recover the existing wallet, and to confirm any other action.
