The turnkey Turtle board solution can be used immediately. Support standard LoRaWAN protocol and RadioShuttle protocol. The included RadioShuttle radio protocol software enables node-to-node communication without additional routers and servers. The Turtle LoRa board by HelTec Automation can run 10 years on AAA batteries (standard or rechargeable NiMH) using the “RadioShuttle” LoRa wireless low-energy protocol software.

About RadioShuttle protocol

RadioShuttle Protocol is a node-to-node LoRa wireless communication protocol software. Compare with LoRaWAN(TM), which is capable of efficiently sending messages in a fast and secure way, any node can work as a gateway. We also provide the MQTT server and IOS / Android APP examples source code.

LoRaWAN^TM	RadioShuttle
Concentrator required	No concentrator required, the station uses regular LoRa module
Network subscription fees (If use MQTT server)	No monthly fees
One large radio cell	Many small independent radio cells
Busy network in a radius of many kilometers	Small networks with no interference
Single point of failure (Concentrator)	Automatic transmitting power adjustment – longer battery life
High latency, larger spreading factor, e.g. SF11 (1320 ms)	Low latency, small spreading factor, e.g. SF7 (120 ms)
