Overview
Clock pulse generator kicad scheme is an open-source printed circuit board by LeftyDeMilo, from the LeftyDeMilo/clock-pulse-generator repository on GitHub. It is a 2-layer board of 35.8 × 15.7 mm with 17 parts on 23 nets, routed with 129 tracks and 8 vias.
It is built around the ATTINY24A-MF. Its parts include 8 resistors, 4 connectors, 2 ICs, 1 capacitor and 1 diode. It belongs with the lEDs and displays boards and the AVR (ATmega, ATtiny) boards of this library.
Main components
1README
readme.mdBreadboard Clock Pulse Generator with manual and automatic operating modes. In manual mode the circuit operates as a debounced button. In automatic mode it operates as a square wave generator. You could bear through a preset list of frequencies in a range from 0.1 Hz to 97 Hz.
Terminal
To check ATtiny24 fuses (and the MCU reaction) you could use avrdude.
$ avrdude -p t24 -c usbaspBrandnew ATtiny24 20SSU responses Fuses OK (E:FF, H:DC, L:E2),
20PU – Fuses OK (E:FF, H:DF, L:62).
Preset fuses:
$ avrdude -p t24 -c usbasp -U lfuse:w:0xE2:m -U hfuse:w:0xDD:m -U efuse:w:0xFE:mArduino IDE

Operating Manual
Use double click to change operating mode. In both modes an LED indicates a voltage level on the PULSE pin.
Manual mode
In manual mode the device operates as a debounced button. The seven segment display indicates a voltage level on the PULSE pin (like an oscilloscope).
Automatic Pulse Mode
In automatic pulse mode the display indicates a current pulse frequency. You could bear though frequencies with a long button click.

Questions
How big is the Clock pulse generator kicad scheme PCB?
It measures 35.8 × 15.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Clock pulse generator kicad scheme use?
17 parts, built around the ATTINY24A-MF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Clock pulse generator kicad scheme KiCad files?
From the LeftyDeMilo/clock-pulse-generator repository on GitHub, at the commit this page was made from: the board is clock_pulse_generator_kicad_scheme/clock_pulse_generator_kicad_scheme.kicad_pcb and its schematic clock_pulse_generator_kicad_scheme/clock_pulse_generator_kicad_scheme.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Clock pulse generator kicad scheme design in my own project?
Its repository states no licence, so its author keeps all rights: ask LeftyDeMilo before reusing the design.
