THIS IS A KIT - YOU WILL HAVE TO ASSEMBLE. The kit includes all parts needed to build the project, including a heavy metal case. The project is based around an Arduino Nano, which runs a modified version of the K3NG Winkey software. Support has been added for SO2R and can communicate with logging software natively as a Winkey device, or using the SO2R Mini Connector. The connector is a small piece of software that translates your logging software OTRSP (Open Two Radio Switching Protocol) and Winkey into a single stream for the device. The hardware and software are fully published, allowing the end-user to customize the device as they see fit.
Assembly is easy and quick. From start to finish, the average kit builder should be able to complete the kit in an hour. Modest skills are required, there are no surface mount ICs or RF connectors. The kit contains everything needed to build a functioning unit.

For more technical users, I2C and Aux buses are available, allowing for inter-device communication, as well as GPIO, for extra features, like interlocking, multi-paddle, band data, and antenna outputs, RTTY generation, and more. There are also pins available for LED indicators of transmitting and receive status. The SO2R Mini is designed to be an inexpensive, yet complete and flexible solution for SO2R contesting. Similarly, the SO2RM can act as a Winkey by itself. This tiny box measures only 10cm long and 5cm tall. All input connectors are 3.5mm TRS jacks. Separate jacks are provided for all inputs, with paddle and PTT outputs combined on a common jack, allowing for a stereo splitting cable to be used for most traditional radios. The SO2R Mini is powered by USB and requires a computer connected for full functionality. When no power is applied, the box automatically shifts transmit and receive audio focus to radio one, although PTT and CW signals are not passed. If the user desires the ability to forgo the computer, the SO2R Mini can be expanded to support transmit and receive control switches and a potentiometer for CW speed control. These features are supported on the circuit board and in software. Just add your own pot and switches.
