Other Parts to Consider
The following are additional parts you may want to consider:
•
Enclosure (example the
100x68x50 mm “clear plastic project box” for
around $3 works well)
•
5V (no buck) or 7V-24V power supply with buck installed (9 volt battery
works)
•
A paddle key to enter Morse code
•
8 ohm speaker to hear the Morse tones
•
1601 LCD with Serial (I2C / SPI) interface
•
Arduino Rotary Encoder module or 10K potentiometer for the
Morse speed setting
•
PS/2 or USB keyboard
The nKeyer is quite flexible and provides a wide range of options to try. The code for the
board has an extensive set of compiled features, most that the nKeyer will support.
