96Boards Consumer Edition Specification v2.0 adds Ethernet, PCIe, expansion connectors

96Boards CE specification v2.0 layout

Linaro’s 96Boards specification was first introduced in 2015 with the launch of Hikey SBC following 96Boards CE specification, which CE standing for Consumer Edition. The standard would define mechanical, electrical, and software requirements to create an ecosystem of low-cost, expandable, compatible, and well-supported boards.  The software requirements were never very well followed, and while the hardware would usually be compliant, some complained about the specifications themselves notably with the lack of Ethernet for the standard version of the 96Boards CE SBC. Linaro has now announced the updated 96Boards CE specification 2.0 that adds ports location for optional Ethernet and PCIe Ethernet connector among other things. The minimum hardware requirements remain the mostly same, except for a few tweaks: Ultra-small low-profile form factor – 85x54x12 mm Extended Version: 85x100x12mm Design is SoC independent (targets 32- and 64-bit SoCs) 0.5 GB RAM (Minimum 4GB recommended for Android) MicroSDHC Socket for up 64GB onboard or expansion flash storage Wi-Fi 802.11g/n and Bluetooth 4.0 […]

LwM2M v1.2 M2M & IoT device management protocol adds support for HTTP and MQTT, LwM2M gateways

LwM2M v1.2

Lightweight M2M (LwM2M) is a REST-based protocol from the Open Mobile Alliance (OMA) for M2M & IoT device management that defines the application layer communication protocol between an LwM2M server and an LwM2M client running on an IoT/embedded device. While LwM2M v1.0 was published in early 2017, we first covered the new protocol a year earlier as Imagination Technologies released the source code for the LwM2M stack running on MIPS Creator Ci40 development board.  Since then we’ve mostly seen the LwM2M protocol supported in cellular LTE IoT modules including Quectel BC66 and u-Blox Sara-R410M, as well as the now-defunct Samsung Artik WiFi IoT modules. LwM2M v1.0 was followed by v1.0.1 and v1.0.2 for bug fixes, and v1.1, but OMA has now announced LwM2M v1.2 protocol that adds the following new features: New transports for LwM2M: MQTT and HTTP Optimizations for the bootstrapping and registration interfaces to reduce the amount of data transmitted during the bootstrapping and registration exchanges respectively. Observation […]

MicroSAM System-on-Module Standard Targets Microcontrollers, IIoT Sensors

MicroSAM Module Architecture

There are plenty of system-on-module standards, but those mostly target application processors such as Intel/AMD x86 processors or Arm Cortex-A based SoCs. PICMG has now added a new IIoT-related open standard with MicroSAM specifying a 32x32mm module for microcontrollers and industrial IoT sensor nodes. MicroSAM standard highlights: Reliable RS422 industrial-grade communications PWM output for motion control applications Direct connectivity to a variety of sensor types (analog voltage, analog current, digital) Low power consumption Power filtering and signal conditioning for embedded installations Dimensions – 32mm x 32mm Latching connectors for secure connectivity Full industrial operating temperature range from -40°C to +85°C One of the advantages often cited for traditional SoMs is that customers don’t have to take care of the complex layout around the processor and RAM, and can simply create a 2-layer baseboard to insert the 6-layer SoM into it. This lowers the development costs and time-to-market. But it’s not really an argument that can be made for microcontroller board, […]

Z-Wave Long Range (LR) Promises Up to 4 Times the Range, 10-year Battery Life

Z-Wave Long Range

ETSI Releases EN 303 645 IoT Security Standard for Consumer Devices

ETSI EN 303 645 IoT Security Standard

To be successful over the long term, IoT must be secure, at least that’s what people say. So in 2016, UL introduced the UL 2900 IoT security standard, but it set the bar so high, that nobody ended up using it. and the UL IoT Security Rating System was introduced last year with various rankings for IoT devices security from bronze to diamond. The rating system was based on various countries/regions standard including ETSI TS 103 645 standard for the European market which defined requirements in terms of software updates, data & cryptography, logical security, system management, privacy protection, protocol security, and processes and documents. The ETSI Technical Committee on Cybersecurity (TC CYBER) has now released an update to TS 103 645 IoT security standard with ETSI EN 303 645 “that establishes a security baseline for internet-connected consumer products and provides a basis for future IoT certification schemes”. There are thirteen cybersecurity provisions – aka the 13 commandments of IoT […]

NFC Wireless Charging Coming Soon to IoT Devices and Wearables

NFC Wireless Charging

NFC is better known for contactless payment and transferring contacts, but one interesting feature is the ability to provide power as we’ve recently seen with batteryless NFC powered E-paper displays. The current NFC implementations can only provide a limited amount of power, but the NFC Forum has recently approved the Wireless Charging Specification that enables wireless charging of small, battery-powered consumer and IoT devices with a smartphone or other NFC charging device at a power transfer rate of up to one watt. One watt is not as much as other similar technologies, but NFC wireless charging (NFC WLC) should be quite more cost-effective since device-specific wireless chargers are not needed. Just take a phone or charger with NFC WLC and all compliant devices could be charged that way. The specification is free to download for NFC Forum members but must be purchased by others. There’s still short abstract available: Wireless Charging allows for wireless charging of small battery-powered devices like […]

SGET SMARC 2.1 Hardware Specification Allows Up to 4 Cameras, 4 Ethernet Interfaces

SMARC 2.1

There are plenty of standards for systems-on-module that are supposed to allow interoperability between vendors. For example vendor 1 may create a Qseven SoM that works with vendor 2’s Qseven compliant carrier board which should accept any Qseven compatible module, although in practice, there are always some small differences that may cause problems. Many of those standards are managed by SGET (Standardization Groups for Embedded Technologies) including SMARC (“Smart Mobility ARChitecture”), Qseven, and Embedded NUC. A recent post on ADLINK Technology alerted us of the publication of SMARC 2.1 hardware specification (PDF) with the following changes: Incorporated Errata 1.1 Rev. 2 (2/9/2017) Updated signal tables with pin number, power domain, termination information… Added details for eDP[0:1]_HPD Added SERDES as alternative function for PCIeC and PCIeD Added MDIO Interface Updated power domains and power sequencing Added two extra GPIOs PCIe Clock Request signals for PCIeA and PCIeBat at previous locations Changed fill order for MIPI CSI (CSI1first, then CSI0) Added CSI […]

UFS 3.1 Storage Devices to Deliver Better Performance, Lower Power Consumption

UFS 3.1 Specification

JEDEC first introduced UFS 3.0 embedded flash in September 2017 with promises of 2.4GB/s transfer rates, and somehow this was bumped to 2.9GB/s (23.2 Gbps) when UFS 3.0 specification was published in January 2018. JEDEC has now published UFS 3.1 specification with the same theoretical performance, but some new features that should improve write performance, random read performance, as well as lower power consumption and costs. Precisely two documents are now available for purchase, unless you work for a JEDEC member, in which case those are free downloads: The Universal Flash Storage (UFS) version 3.1, JESD220E. An optional new companion standard, JESD220-3: UFS Host Performance Booster (HPB) Extension. The first defines three main improvements as part of UFS 3.1: Write Booster – an SLC non-volatile cache that amplifies write speed DeepSleep – a new UFS device low power state targeting lower-cost systems that share UFS voltage regulators with other functions Performance Throttling Notification – allows the UFS device to notify […]
