Solid performance

We are using three of these in our lab setup. They maintain setpoints very well. Would love to see a version with WiFi connectivity in the future.

Great value, minor display issue

Works exactly as described for our prototype testing. The only reason for 4 stars is that the OLED display angle is a bit narrow, but functionality is top-notch.

Best controller in this price range

I have tried several generic controllers, but this one offers the best stability. The digital PID really makes a difference compared to analog potentiometers.

Easy to integrate

Documentation was clear enough to get this running in under an hour. The heating and cooling switching is smooth without any audible clicks from the relay.

Compact and powerful

Impressed by how much power this little board can handle. It drives my TEC module efficiently without getting too hot itself. Highly recommended for precision tasks.

Perfect for my DIY cooling project

The PID tuning is incredibly stable. I used this to control a small incubator and the temperature fluctuation is less than 0.1°C. The bidirectional feature works flawlessly.

5 FAQ

Q: Does it come with the NTC sensor included?

A: The standard package includes the control board only. The NTC 10K thermistor sensor needs to be purchased separately or sourced from your existing inventory.

Q: Can this module drive a 12V 4A TEC directly?

A: Yes, the TCB-NE supports up to 5A continuous output, so it can safely drive a 12V 4A thermoelectric cooler.

Q: Is there a way to monitor the temperature remotely?

A: This specific model features a local OLED display. For remote monitoring, you would need to utilize the optional UART TTL interface to connect to a microcontroller or PC.

Q: What happens if the power polarity is reversed?

A: The board includes reverse polarity protection. If connected incorrectly, the unit will simply not turn on, preventing damage to the components.

Q: Can I use this for heating only applications?

A: Absolutely. While it supports bidirectional control, you can configure the PID parameters to operate strictly in heating mode if your application requires it.
