Multi-hop compatible 920MHz wireless module

A 920MHz wireless module compatible with ad hoc multi-hop networks that performs dynamic route exploration.

The "IM920s series" is a 920MHz wireless module that dynamically constructs routing information and forms an ad-hoc multi-hop network with up to 5 layers. It enables stable communication even in non-line-of-sight conditions or with moving devices. Additionally, unicast and broadcast transmission options are available. The multi-hop communication topology includes a relay operation mode with low communication load, as well as mesh and tree networks that automatically exchange routes, which can be used with command switching. It has obtained technical compliance certification, so no licenses or application procedures are required. Complicated radio law-related controls are handled internally. A retransmission function has been added, making external control easier. The interface uses a synchronous serial interface with IM commands. It is compatible with other IM series, allowing for easy control from external microcontrollers. An external antenna type is also available, so you can choose according to your usage environment, such as when using a metal case or when you want to stabilize communication further.
