The closed‑loop control works like this:
The JUQ103 is the latest flagship model from JuqTech, a fast‑growing hardware startup that has made a name for itself in the ultra‑compact, high‑performance device market. Officially marketed as a “Portable Power‑Performance Hub”, the JUQ103 merges the capabilities of a mini‑PC, a high‑speed external GPU (eGPU), and a 5G‑enabled edge‑computing node into a single 200‑gram chassis. juq103 hot
TL;DR: The JUQ103 is a pocket‑sized, plug‑and‑play powerhouse that delivers desktop‑grade computing on the go. The closed‑loop control works like this:
| Parameter | Typical Value | Notes | |-----------|----------------|-------| | Part Number | JUQ103 Hot | “Hot” denotes the temperature‑controlled version (a “Cold” variant exists for passive heating). | | Form Factor | 10 mm × 10 mm × 3 mm (SMD) | Designed for PCB mounting; also sold as a “stand‑alone” module with pins. | | Power Rating | 1 W – 5 W (adjustable) | Set via external driver; max continuous dissipation 5 W. | | Operating Voltage | 5 V – 24 V DC | Wide range to accommodate Arduino, Raspberry Pi, or dedicated drivers. | | Temperature Range | 30 °C – 250 °C (±2 °C) | Controlled by an integrated thermistor (NTC 10 kΩ). | | Control Interface | PWM or analog voltage | Most drivers accept 0‑5 V analog or 0‑100 % PWM. | | Response Time | < 0.8 s to 90 % of setpoint | Fast heating makes it ideal for quick reflow cycles. | | Safety Features | Over‑temperature shutdown, built‑in fuse (250 mA) | Prevents catastrophic failure. | | Certifications | RoHS, CE (EU), FCC (US) | Suitable for commercial prototyping. | The JUQ103 is the latest flagship model from
The module consists of a thin ceramic heater laminated onto a copper trace, with a NTC thermistor embedded for closed‑loop temperature feedback. A tiny MOSFET driver (often a separate board) reads the thermistor and modulates the heater’s power.
