Q: What is the benefit of the PAN3060 chip solution?
A: The PAN3060 utilizing ChirpIoT™ technology offers a cost-effective yet robust spread spectrum solution, providing high anti-interference performance and long-range connectivity comparable to standard LoRa solutions in industrial environments.
Q: How does the Automatic Relay networking work?
A: The module can be configured as a relay node. It automatically passes data between out-of-range nodes, effectively multi-level jumping to bypass obstacles and extend the network coverage beyond the single-hop 5km limit.
Q: Can I update the firmware after the module is soldered?
A: Yes. The module supports IAP (In-Application Programming). You can perform firmware updates online through the UART interface without needing to physically remove or reprogram the module via dedicated hardware pins.
Q: What power supply is required for 20dBm output?
A: The module operates from 2.6V to 5.5V. However, to guarantee the full 20dBm (100mW) transmit power, a stable power supply of at least 5V is recommended. At lower voltages, the transmit power may decrease slightly.
Q: How compact is this module for high-density PCBs?
A: It is designed with an ultra-small volume footprint using a stamp-hole (SMD) package, making it significantly smaller than standard UART modules. It is ideal for high-density motherboard integration where space is at a premium.
