This project is a temperature display and alarm system designed for educational purposes as part of the IA 2209 - Microcontroller Laboratory course.
Temp is an open-source printed circuit board by AvishkaVishwa, from the AvishkaVishwa/Microcontroller-Design-Project-Temperature-Monitoring-System repository on GitHub. It is a 2-layer board of 61.3 × 87 mm with 38 parts on 55 nets, routed with 256 tracks and 6 vias.
It is built around the ATMEGA328P-PU, DHT11 and CC56-12SURKWA. Its parts include 11 resistors, 7 capacitors, 7 diodes, 5 ICs and 1 connector. It belongs with the lEDs and displays boards and the AVR (ATmega, ATtiny) boards of this library.
This project is part of the IA 2209 - Microcontroller Laboratory course. It involves creating a microcontroller-based temperature monitoring system with various features including temperature display, alarm, and range indication using LEDs.

angelozyh/STM32-Environmental-Monitor-PCB
A custom 2-layer PCB designed in KiCad for an STM32-based environmental monitoring system. The board integrates an STM32 NUCLEO-F303K8, BME280 environmental sensor, dual SN74HC595 shift registers, a 4-digit 7-segment…
Spac3y/seg7-85
A 4-digit 7-segment display driven by an ATtiny85, scrolling a text message across the display.
It measures 61.3 × 87 mm and has 2 copper layers, 1.6 mm thick.
38 parts, built around the ATMEGA328P-PU, DHT11 and CC56-12SURKWA. 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.
From the AvishkaVishwa/Microcontroller-Design-Project-Temperature-Monitoring-System repository on GitHub, at the commit this page was made from: the board is PCB Design Using KiCAD/temp.kicad_pcb and its schematic PCB Design Using KiCAD/temp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask AvishkaVishwa before reusing the design.
