Overview
Desktop Hardware Monitor is an open-source printed circuit board by aapaetsch, from the aapaetsch/HardwareMonitorArduino repository on GitHub. It is a 2-layer board of 106 × 71.3 mm with 44 parts on 80 nets, routed with 609 tracks and 18 vias.
It is built around the ATMEGA328-PU, DHT11 and SM420561N, with the 74HC164 and 74LS04PC among its other parts. Its parts include 13 ICs, 6 transistors, 3 connectors, 2 capacitors and 1 switch. It belongs with the AVR (ATmega, ATtiny) boards of this library.

README
README.mdRough Overview of the project so far:
- Desktop Hardware Monitor: Contains the PCB Files for the project.
- Hardware_Monitor: Contains the arduino code for an arduino microcontroller, currently this is an ATMEGA328p-pu.
- This will be used to drive 6x7 segment displays (common cathode) and (hopefully) 2 i2c 128X64px screens.
- Drivers for the I2C displays still need to be coded.
- Some logic from the output pins will need to be offloaded to external IC chips
- So far 74HC164 8-bit Shift Register, 74LS04 hex inverter, 74LS138
- Serial inverters are bulky, maybe V-USB if the chip has enough storage after the program is close to finished in size...
- HardwareMonitorArduino: Contains the code related to a C# program that will run on the host pc. (Incomplete) Will share code with my DesktopHardwareMonitor electron application.
V1 PCB - No Input USB and requires a redesign as it does not fit in the 100mm x 100mm limit for JLPCB

Questions
How big is the Desktop Hardware Monitor PCB?
It measures 106 × 71.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Desktop Hardware Monitor use?
44 parts, built around the ATMEGA328-PU, DHT11, SM420561N and 74HC164. 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 Desktop Hardware Monitor KiCad files?
From the aapaetsch/HardwareMonitorArduino repository on GitHub, at the commit this page was made from: the board is Desktop Hardware Monitor/Desktop Hardware Monitor.kicad_pcb and its schematic Desktop Hardware Monitor/Desktop Hardware Monitor V1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Desktop Hardware Monitor design in my own project?
Its repository states no licence, so its author keeps all rights: ask aapaetsch before reusing the design.
