Digital Temperature Controller Module – 4-Digit LED & NTC Sensor
Digital Temperature Controller Module with 4-Digit LED Display
Build your own precision soldering station or custom temperature-control device with this compact Digital Temperature Controller Module. Featuring a high-brightness 4-digit LED readout, a smooth rotary encoder for stepless adjustment, and a high-precision NTC sensor, this circuit board gives hobbyists, makers, and electronics enthusiasts rock-solid temperature regulation for T12, JBC210, and JBC245 soldering iron handles — or virtually any 12–24V DC application.
Made in Mainland China.
Key Features
- High-Precision NTC Temperature Sensing: Metal NTC probe with high-temperature-resistant insulated wire delivers real-time temperature detection with just ±1 °C error tolerance, ensuring consistent, stable output for demanding DIY and professional projects.
- Clear 4-Digit LED Readout: High-brightness LED display module remains easily readable even under strong ambient light, letting you check and adjust the current temperature at a glance.
- Durable FR-4 PCB Construction: Built on a high-quality FR-4 fiberglass PCB with high-conductivity copper traces for excellent corrosion resistance, oxidation resistance, and heat dissipation — engineered for long-term, reliable operation.
- Smooth Stepless Adjustment: High-sensitivity rotary encoder potentiometer supports wide-range, stepless temperature setting so you can dial in your exact target quickly and accurately — no complicated multi-step menus.
- Multi-Layer Circuit Protection: Built-in ESD protection diode, overcurrent protection precision resistor, and voltage-stabilising capacitor guard against overvoltage, overcurrent, and static discharge, keeping your components and connected devices safe.
- Universal Compatibility: Standard XH2.54 pin ports are compatible with T12, JBC210, and JBC245 soldering iron handles and most 12–24V DC power supplies — ideal for DIY soldering station builds, electronic maintenance, small industrial temperature monitoring, and custom temperature-control applications.
