SBC is compact for factory automation and IoT gateway systems

Equipped with on-board memory and storage and dual Gigabit Ethernet support, the Pico-APL4 is a compact, cost-effective single board computer (SBC) from Aaeon. It is, says the company, suitable for factory automation and IoT gateway systems.

This latest Pico form factor board from Aaeon is powered by an Intel Atom, Pentium N4200, or Celeron N3350 processor. By fitting the controller with up to 4Gbyte of on-board DDR3L memory and up to 64Gbyte of on-board eMMC storage, Aaeon believes not only is the board more resistant to the shocks and vibrations regularly experienced in industrial settings, but it will also cut application development times as customers will not need to test the compatibility of external memory and storage.

The flexible Pico-APL4 houses USB ports and connectors, COM ports, a HDMI port and optional eDP. There’s also a four-bit DIO to manage peripherals and an optional four-lane MIPI-CSI. For expansion there are M.2 B and E keys for the connection of additional storage and WiFi/Bluetooth modules. An optional board-to-board interface, allows customers to extend the IO interface and add a larger DIO.

Aaeon was established in 1992. It designs and manufactures intelligent IoT solutions and high quality computing platforms, including industrial motherboards and systems, industrial displays, rugged tablets, embedded controllers, network appliances and related accessories, as well as integrated solutions. Aaeon also has the hardware and services for premier OEM/ODMs and system integrators worldwide. The company is an Associate Member of the Intel Internet of Things Solutions Alliance, and offers customised end-to-end services from initial product conceptualisation and board product development to mass manufacturing and after-sales service programs.

Mouser offers TI’s digital humidity and temperature sensor for smart devices

Distributor Mouser Electronics has added Texas Instruments’ HDC2080 humidity and temperature digital sensor. It offers high accuracy and low power consumption in a compact package, reports the distributor and is suitable for a range of IoT and environment monitoring applications.

The TI HDC2080 humidity and temperature digital sensor is a capacitive-based device that uses an integrated heating element to dissipate moisture and condensation. The sensor integrates multiple digital features, allowing for the use of programmable input thresholds to deliver system wake-ups and alerts without needing to rely on a microcontroller to monitor the system. The HDC2080 sensor’s low power consumption allows developers to place their microcontrollers in deep sleep mode, because the sensor can initiate measurements without input from a microcontroller. The high-performance sensors offer a typical humidity accuracy of ± two per cent and a typical temperature accuracy of ±0.2 degrees C.

The sensor features an auto-measurement mode to initiate humidity and temperature measurements, enabling efficient performance in applications with power-budget restrictions. The sensor is designed for battery-operated systems and supports a supply voltage range of 1.62 to 3.6V. With an operating temperature range of minus 40 to 85 degrees C, the sensors can be safely used in applications such as home appliances, smart home devices, smart thermostats, HVAC systems and inkjet printers.

The HDC2080 humidity and temperature digital sensor is supported by the HDC2080EVM, a simple plug-and-play platform that features an MSP430F5528 microcontroller and a USB interface, for communication between the HDC2080 sensor and a PC. The module’s included software graphically logs humidity and temperature data, and the module also allows access to the sensor’s configuration registers.

Mouser claims to stock the world’s widest selection of the latest semiconductors and electronic components for the newest design projects. Mouser Electronics’ website is continually updated and offers advanced search methods to help customers quickly locate inventory. Mouser.com also houses data sheets, supplier-specific reference designs, application notes, technical design information, and engineering tools.

Farnell element14 offers Microchip SAM L10 and SAM L11 eval kits for IoT

Development distributor, Farnell element14, has announced the availability of the Microchip SAM L10 and SAM L11 Xplained Pro evaluation kits and associated microcontrollers. The devices are claimed to be the industry’s lowest-power 32-bit microcontrollers as well as the first to offer chip-level security and Arm TrustZone technology.

According to Farnell element14, the SAM L10 is the industry’s lowest power microcontroller in this class and allows users to develop secured applications without the battery constraints of less power-efficient microcontrollers. Its low power consumption makes it suitable for a range of IoT applications in areas such as wearable devices, gaming controls, energy harvesting, smart pens and low-power industrial sensor nodes.

The SAM L11 features integrated hardware security for IoT nodes, remote keypads and authentication systems for smart cities and home automation, industrial automation or medical devices.

The microcontrollers run at 32MHz with memory configuration of up to 64kbyte flash and 16kbyte SRAM. They also have low power consumption and an enhanced peripheral touch controller for capacitive touch interfaces to be incorporated into appliances, fitness trackers, automotive door handles, key pads or remote controls. The interface is four times faster than previous generations of peripheral touch controller and provides highly-responsive and accurate touch sensing, says Farnell element14. It is supported by the QTouch Configurator and QTouch Modular library, designed to add elegant touch interfaces to designers’ applications. Both devices are available in 24- and 32-pin package options.

The SAM L10 and SAM L11 are built with picoPower technology to provide flexible power saving modes. They are also claimed to be the industry’s lowest power microcontroller in their class with an EEMBC certified ULPMark of 405.

Power debugging and data visualiser tools are available to monitor and analyse power consumption in real time, helping developers optimise system designs for lower power consumption with improvements in battery life.

The chip-level security incorporated into SAM L11 MCUs is based on Arm TrustZone technology to help protect against both physical and remote attacks, together with a security framework to simplify the implementation of security. IoT nodes driven by a SAM L11 provide strong resistance to remote software attacks, thereby increasing the reliability and avoiding any downtime of the critical functions of the nodes, says the company. The chip-level tamper resistance will help protect from cloning and intellectual property theft.

Both microcontrollers are available as development kits: the SAM L10 and SAM L11 Xplained Pro Evaluation Kits. These are fully supported with security, low-power and touch demos to accelerate development and help customers get their designs to market faster.
