About the Temperature controller PCB

Temperature controller is an open source NXP PCB design by iams-yb-lab, published on GitHub. It is a 4-layer board measuring 163 × 100 mm, with 108 components from 34 distinct parts.

Its main chip is the TEENSY4.1, from the NXP family. Other key parts include the MAX1968EUI+T, C2862740, ADR4525 and AD7124-8BCPZ. By type, the board carries 51 capacitors, 36 resistors, 8 connectors, 5 ICs, 5 diodes and 2 inductors.

It belongs with the sensors and test & measurement designs in this gallery.

From the project

A simple, low-cost, modular, multi-channel temperature controller for holding a lab laser steady enough to stay injection-locked. The figure of merit is relative stability — keeping the temperature put — not absolute accuracy. A vertical slice around an AD7124-8 24-bit ADC and a

A simple, low-cost, modular, multi-channel temperature controller for holding a lab laser steady enough to stay injection-locked. The figure of merit is relative stability — keeping the temperature put — not absolute accuracy. A vertical slice around an AD7124-8 24-bit ADC and a Teensy 4.1 (C++), borrowing only the proven MAX1968 TEC power stage from the open-source Sinara Thermostat.

Temperature controller: common questions

What microcontroller does the Temperature controller use?

The Temperature controller is built around the TEENSY4.1, from the NXP family.

How big is the Temperature controller PCB?

The Temperature controller measures 163 × 100 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Temperature controller?

108 components, from 34 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Temperature controller design files?

From the iams-yb-lab/temperature-controller repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Temperature controller design in my own project?

The repository has no license, so all rights stay with iams-yb-lab. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Temperature controller without the hardware?

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