Aistin Bus24 - Intelligent Open Interface Standard for Low Power Internet of Things

Aistin Bus24 is next generation solution for IOT applications where low power and small size are required. The Aistin Bus24 connects IOT components such as sensors and actuators to processing units having Aistin Bus24 interface in a cost effective and fast manner.

Aistin Bus24 is open standard supported by iProtoXi which is a Finnish IOT sensor technology and products provider.

Aistin Bus24 is a combination of standard IO buses, like I2C, SPI, UART and one wire, with intelligent power management signals to enable long battery life. Development kits with the Aistin Bus24 provide low cost and fast deployment of sensors while developing the IOT nodes or corresponding applications.

Our target is to expand the usage of Aistin Bus24 worldwide.

There's a huge amount of different kind of electronic development boards. While most of them are manufacturer specific, one open platform, Arduino, is getting more and more popular. Typically, both the manufacturer specific and Arduino boards have some kind of connector for getting more functionality with add-on boards. However in all cases there exist two major problems:

  1. There's no connector standard for add-on boards
  2. Add-on boards make the physical size of the system big and therefore clumsy for e.g. wearables

To address these problems, a team of experienced engineers with Nokia background started developing an interface that was named as AISTIN BUS24. First version of the bus was implemented in 2012 by iProtoXi and the first compatible product line was brought to market in 2013.

During the past two years the Aistin Bus24 has still been adjusted to better match different kind of needs. Now in 2015 it is complete enough to be published as an open standard.

In the figure 3 is shown the tiny connector - only 7 x 2.5 millimeters - and the primary signals of the Aistin Bus24. The whole documentation of the standard can be freely downloaded here Download
