TermDriver 2 is a USB-to-serial interface with a built-in screen. It supports baud rates from 1200 to 2 Mbit, all the while showing critical line status and traffic on its tiny yet full-featured monitor. The terminal emulation supports standard ANSI escape codes, so colors and layout are faithfully reproduced on the TermDriver display.

You can use TermDriver 2 just like any other fully featured USB serial adapter. It supports high speeds and includes a 32 KB input buffer, capable of supplying up to 350 mA at 3.3 V. TermDriver 2 can also operate independently of USB, allowing it to be added as a console to embedded systems, such as a Raspberry Pi.

By Makers For Makers

As independent creators ourselves, we spent a long time thinking about what we wanted from a USB-to-serial adapter. We’ve included several features that will save you time compared to other solutions:

• See the serial code immediately, so you can confirm the device it's talking to
• Refer to a connection schematic on the screen—no more squinting at a hard-to-read silkscreened diagram
• Get instant confirmation when the PC establishes a connection
• Bright and clear indicators for TX, RX, along with DTR and CTS control signals

The firmware for the onboard dual-core RP2040 is carefully written for maximum performance. One core handles the USB-to-UART communication, while the second core is responsible for rendering the display.
