Other key parts include the LM393DR. By type, the board carries 14 resistors, 12 diodes, 12 capacitors, 10 jumpers, 7 connectors and 6 test points.

From the project

MuKOB (μKOB) - MorseKOB for a microcontroller-based platform.

Raspberry Pi Pico W (RP2040 CPU) based device with a built-in display and a terminal interface. Uses built-in wifi to connect to the MorseKOB Server.

It interfaces to a KOB, Key + Sounder, Key + Tone, Paddle + Tone, etc. to provide Morse input and output. The device can operate completely stand-alone (using the display-touchscreen) or it can connect to a VT-220 terminal (or emulator like Putty) to provide a larger interface and allow keyboard input.
