Ai-Thinker01 AI-Thinker Ai-SG Series
Not just a “wireless module”, but an ultimate RF front-end module
The Ai-SG01 / Ai-SG01-P are based on Panqi Micro’s next-generation PAN3120 RF chip, designed for industrial and IoT scenarios with extremely high requirements for size, performance, and stability.
- Frequency bands: 420–445 MHz, 470–510 MHz (optional)
- Receiver sensitivity: –121 dBm
- Transmit power: +20 dBm
- Size: 12 × 13 × 2.4 mm
- SMD-16 / castellated (stamp-hole) interface
Its core advantage lies in extreme miniaturization combined with top-tier RF performance.

03 Ai-SG01-P
Industrial-grade module built for range + power
Solves thermal accumulation risks during long-term high-power operation
One of the key highlights of Ai-SG01-P:
- PAE up to 41>#/span###
- Continuous transmission at 30 dBm
- Module surface temperature only 32–45 °C
- Antenna impedance mismatch protection
- Stable operation under no-load and abnormal conditions
Completely solves the long-standing “antenna burns the module” problem
Designed specifically for real industrial environments:
- Antenna impedance mismatch protection
- Stable operation under no-load and abnormal conditions
Even when:
- Antenna is not connected
- Antenna is mismatched
- Misoperation occurs on site
- The module continues to operate reliably.
