About the PCB-Temperature-Controller

PCB-Temperature-Controller is an open source AVR/Arduino PCB design by MbFredys, published on GitHub under the CERN-OHL-W-2.0 license. It is a 2-layer board measuring 90.8 × 56.5 mm, with 68 components from 33 distinct parts.

Its main chip is the ATmega328P-AU, from the AVR/Arduino family. Other key parts include the 74LS155, LM1117-3.3, CA56-12EWA, 74HC595 and AD623. By type, the board carries 24 resistors, 11 capacitors, 10 ICs, 9 transistors, 4 connectors and 4 switches.

It belongs with the sensors and displays & leds designs in this gallery.

From the project

Temperature-controller PCB design exercise documenting sensing, control, power, and output-interface implementation.

This is a temperature controller PCB design that allows for precise temperature control with the following features:

1. 🌡️ Displays the current temperature value. 2. 🎯 Displays the desired temperature value. 3. ⬆️⬇️ Two buttons to raise and lower the temperature. 4. 🔌 Accepts a supply voltage of 100-240V AC. 5. 📶 Bluetooth communication. 6. 🌡️ Allows for the use of thermocouple and PT100 type sensors.

PCB-Temperature-Controller: common questions

What microcontroller does the PCB-Temperature-Controller use?

The PCB-Temperature-Controller is built around the ATmega328P-AU, from the AVR/Arduino family.

How big is the PCB-Temperature-Controller?

The PCB-Temperature-Controller measures 90.8 × 56.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PCB-Temperature-Controller?

68 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the PCB-Temperature-Controller design files?

From the MbFredys/PCB-Temperature-Controller repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the PCB-Temperature-Controller design in my own project?

Yes, under the terms of its CERN-OHL-W-2.0 license, which MbFredys chose for the repository.

Can I test firmware for the PCB-Temperature-Controller without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
