Other key parts include the LM393DR and FT231XQ. By type, the board carries 16 resistors, 14 capacitors, 10 diodes, 5 connectors, 3 jumpers and 2 ICs.

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.
