The project documentation with all the details which including assembly details, firmware uploading, compilation, and usage instructions are available at the project repository's wiki. Compare, Data Logging (RS-232, USB), Hold, Min/Max Auto True RMS. All the design files and firmware source code are available at the project repository at . Digi-Key’s tools are uniquely paired with access to the world’s largest selection of electronic components to help you meet your design challenges head-on. To facilitate future upgrades and modifications, the PIC16F886 MCU sticks with the standard 28-pin DIP package. To reduce the dimension of the PCB this unit is designed with combining both through-hole and surface mount components. The most recommended working voltage is 9V.

This keyer is designed to work with 7V to 16V DC input voltage. To submit keystrokes user can use any serial terminal software such as PuTTY, Hyper Terminal, Minicom, etc.

In most of the operating systems, this interface works without installing any additional device drivers. It emulates a virtual serial terminal to transfer keystrokes to the keyer.

The USB interface of this unit is designed to work with most of the operating systems.
