Product introduction
What’s this?
The turnkey Turtle board solution is ready for immediate use, supporting both the standard LoRaWAN protocol and RadioShuttle protocol.
Main Features
The turnkey Turtle board solution is capable of immediate use and supports the standard LoRaWAN protocol as well as the RadioShuttle protocol. The included RadioShuttle radio protocol software enables node-to-node communication without the need for additional routers and servers. The Turtle LoRa board by HelTec Automation can operate for 10 years on AAA batteries (standard or rechargeable NiMH) using the “RadioShuttle” LoRa wireless low-energy protocol software.
