TQ-Systems (Germany) introduced their TQMa8xx and TQMa8xxs embedded modules that feature three, and respectively two CAN FD interfaces.

The TQMa8xx module offers integrated graphics, a DSP (Digital Signal Processor) for audio processing, and security-related functions. To meet various requirements, three CPU (Central Processing Unit) alternatives with a dual-core or quad-core ARM Cortex-A35 processor are available. Each core supports a clock rate of up to 1.2 GHz. There are a variety of interfaces available, including the three CAN FD interfaces, two Ethernet, three USB, four UART, and more. Additionally, up to four SPI, up to 32 GPIOs, and up to eight I²C ports are supported. Slots for an SD card and PCIe are available. The device features up to 64-GiB eMMC memory, and up to 256-MiB quad SPI NOR, an Eeprom, as well as an up to 2-GB DDR3L.

The board dimensions of 55 mm x 44 mm (2.2" x 1.7") provide a 280-pins board-to-board plug-in system. It also features a temperature sensor and an RTC (real-time clock). The extended operating temperature ranges from -40 °C to +85 °C. The unit requires a power supply of 3.3 VDC, and it consumes 4 W. Supported operating systems include Linux, QNX (on request), or Android (on request).

The TQMa8xxs module dimensioning 82 mm x 50 mm (3.2" x 2") includes the Smarc 2.0/2.1 board-to-board plug-in system with 314 pins. It provides similar (but less) functionality and interfacing features than the TQMa8xx board.

• Graphics with 4K support
• Security functions
• Integrated 1x Cortex M4 CPU (Real Time / Security)
• Low power consumption (typ. 4 W)
• DSP for audio processing
• 3x CAN FD

Designing Embedded Systems and the Internet of Things (IoT) with the ARM mbed

Designing Embedded Systems and the Internet of Things (IoT) with the ARM mbed offers a comprehensible guide to the development of ARM mbed and includes a variety of topics on the subject from the basics to the advanced.

ARM mbed is a platform and operating system based on 32-bit ARM Cortex-M microcontrollers. This vital resource puts the focus on ARM mbed NXP LPC1768 and FRDM-K64F evaluation boards. NXP LPC1768 owns powerful features such as a fast microcontroller, various digital and analog I/Os, various serial communication interfaces, and a very easy to use Web-based compiler. It is one of the most popular kits that are used to study and develop IoT projects. The FRDM-K64F is relatively new and mostly compatible with NXP LPC1768 but with even more powerful features.

This book is an ideal guide that comes in four sections: Getting Started with the ARM mbed, Covering the Basics, Advanced Topics, and Case Studies.
