THE RTOS-SUPPORTING BOARD WITH A MICROCHIP PIC32MZ 32-bit MCU and a cellular Telit module is based on a modular hardware design principle. It simplifies the integration of custom-specific applications and communication standards into a single solution platform. Target applications range from cloud-connected oil tanks and intelligent waste bins up to cloud-connected gateway systems for manufacturing robots.

“Our Ping Pong platform offers software engineers an application-ready, pre-validated Ping Pong data exchange mechanism which eases the IoT integration of any field device,” explains Ben Hoelke, CEO of Round Solutions. “With the supplied Round Solutions Open Source Ping Pong Software Development Kits, the platform can be configured for nearly all IoT/M2M applications, such as sensor reading, asset tracking, routers, measurement technology, telemetry, and security control. Thus, Round Solutions’ Ping Pong offers companies wanting to transfer their data to IoT cloud-servers a complete solution including software libraries and source code.”

The hardware platform offers high-speed cellular modules for IoT connectivity as well as numerous interfaces to the field – which can also be controlled via the cloud. The interfaces include, for example, CAN, Ethernet, and USB as well as a GNSS (Global Navigation Satellite System). Developers can add various expansion cards to create a number of application scenarios. Application-ready expansion cards are available for WLAN, Bluetooth, I/O, Iridium satellite communications, ISM/RF, Sig Fox, NFC/RFID, and camera connectivity. All functions are ready for use as soon as the expansion cards are attached to the motherboard.

The product comes with both wired and wireless connectivity. The device is available in two open-source SW versions. While the RTOS version comes with the 32-bit micro-controller running in C/C++, the Linux version uses the ARM Cortex processor for more functionality and applications.

The company also offers open source firmware and software for the board, which enables developers to develop custom firmware for the device. The collected data can be sent to an IoT cloud, offering ways for tools to monitor, visualize, remotely maintain, and control the board. The graphical user interface of the IoT cloud is available through any web browser and through smartphones and tablets.

With m2m AIR SIM cards, the stable data transfer between Ping Pong and the cloud is enabled. Through roaming it is always network active. The product can be used in industries such as industrial automation, food industry, automotive, chemical, consumer goods, or security.
