Low-Profile SDM Signage Board Features Whiskey Lake-U

By Eric Brown

Axiomtek has launched an SDM form-factor “SDM500L” signage board with an 8th Gen Whiskey Lake-U processor with triple 4K display support, up to 32 GB RAM, 3x M.2 sockets, and extended temperature support.

Like the 6th Gen Skylake-based Nexcom NDiS S538 that we covered earlier this week, Axiomtek’s new SDM500L signage computer conforms to Intel’s Smart Display Module-Large (SDM-L) form factor, a sleeker version of its OPS (Open Pluggable Specification). It’s similarly designed to be integrated with SDM compliant displays via a PCIe x8 edge interface in special cabinetry aimed at locations with space constraints. Like OPS, SDM also supports remote management.

Like the Nexcom product, the 175 x 100 x 1.6mm SDM500L board lacks external housing and offers a mounting bracket and panel for the coastline ports. This would appear to boost the width to the SDM-L standard 20mm. The product lacks the fan and top covering of the NDiS S538.

Axiomtek offers an optional SDB100 peripheral interface board (PIB) per the SDM spec to house the board for testing before placing it into a custom enclosure. It offered no further details on the SDB100, however.

The SDM500L is designed for digital signage, interactive flat panel displays, interactive touch computers, video walls, bedside terminals for hospital patients, and factory automation solutions. The system is equipped with a choice of Intel’s 8th Gen Core i7/i5/i3 Whiskey Lake U-series processors with Intel AMT 12 support. No OS support was listed.

Triple independent 4K displays are available via a coastline HDMI 1.4 port (4096 x 2160 @ 30p) plus HDMI 2.0 (4096 x 2160 @ 60p) and DP 1.2 (4096 x 2304 @ 60p) interfaces expressed via the PCIe x8 connector. There’s also an audio mic/headphone combo jack.

The board supports up to 32GB DDR4-2400 via dual sockets. There are 4x USB 3.0 host ports and single USB Type-C and GbE ports. The latter offers Wake-on-LAN, and it supports Intel vPro when using a Core i5 or i7 CPU model.

An M.2 E-key slot can load a WiFi/Bluetooth module, and there are M.2 M-key and B-key slots for SSD storage. The PCIe golden finger expresses a fifth USB 3.0 interface, as well as 2x I2C, a serial interface, and +12V & +3.3VBS power input, in addition to the HDMI and DP connections.

The SDM500L is further equipped with a watchdog, a Lithium 3V/220mAH battery, a reset button, and dual antenna mounts. There’s humidity resistance and a 0 to 60ºC operating range.

Further information

The SDM500L will be available this month at an undisclosed price. More information may be found in Axiomtek’s SDM500L announcement and product page.

Congatec Rolls Out Ten Modules Based on Coffee Lake H Processors

Congatec has announced 10 new COM Express Type 6 modules featuring the latest Intel embedded processor technology. The four Intel Xeon, three Intel Core, two Intel Celeron and one Intel Pentium processors are all based on the same Intel microarchitecture (codenamed Coffee Lake H). This enables Congatec to provide all 10 new processors on one COM Express module design: the conga-TS370. A total of 14 processor module variants are now available on this single microarchitecture, offering extremely wide scalability.

The spearhead in terms of computing power is the 45 W 6-core module with 2.8 GHz Intel Xeon E-2276ME processor. It provides the highest embedded computing performance with integrated high-performance processor graphics currently available worldwide, while the 2.4 GHz Intel Celeron G4930E processor module with 35 watts sets the new price-performance benchmark.

Particularly noteworthy are the two 6-core Congatec modules with a TDP of 25 W offered on Intel Xeon E-2276ML and Intel Core i7-9850HL processors. They enable developers to create completely passively cooled embedded edge computing systems that can run up to 12 standalone virtual machines in parallel thanks to hyperthreading. This allows operation even in fully sealed systems, under the harshest environmental conditions and with the highest IP protection. The same applies to the two quad-core modules with Intel Xeon E-2254ML or Intel Core i3-9100HL processor as well as the Intel Celeron G4932E processor-based module, all featuring a–partly configurable –TDP of 25 W.

Other applications besides embedded edge computing including classic high-end medical imaging systems and HMIs as well as high-end gaming, infotainment and digital signage systems that require best-in-class computing power and throughput on a single die in tandem with the Intel graphics technology.

650 W Modular Power Supplies Provide MoPP Isolation

TDK has announced the introduction of the TDK-Lambda brand QM4 modular power supplies rated at 550 W to 650 W. This further extends the QM series which can provide up to 1500 W output power. The QM4 models are available with up to 10 outputs, have full MoPPs (Means of Patient Protection) isolation and low acoustic noise. With medical and industrial safety certifications, the power supplies are suitable for use in medical, test and measurement, communications and broadcast equipment.

Accepting a wide range 90 VAC to 264 VAC, 47-63 Hz input (440 Hz with reduced PFC), the QM4 can deliver 550 W at low line and 650 W with a high line 180-264 VAC input.  With its modular construction, the series can be configured using a simple on-line configurator to provide 1 to 10 independently regulated outputs and include individual output good signal and remote on/off functions. The QM series module output voltages range from 2.8 V to 105.6 V and have output power levels from 300 W to 1200 W. A further subset of option modules provides an AC Fail signal, standby voltages (up to 12 V, up to 2 A), global remote on/off and PMBus communications. Overall case dimensions for the QM4 are 108 mm x 63.3 mm x 270 mm (W x H x D).

The QM4 will operate in ambient temperatures of -20 to +70°C (-40°C start-up), with output power and output current linearly derating above 50°C to 50% at 70°C. With efficiencies of up to 91%, less internal heat is generated allowing the use of a low speed cooling fan to reduce audible noise. A lower airflow speed also significantly reduces the ingress of dirt and other contaminants, improving product reliability. All models in the QM series have a seven-year warranty as standard.

The power supply has 4,000 VAC (2 x MoPPs) input to output, 1,500 VAC (1 x MoPP) input to ground and 1,500 VAC (1 x MoPP) output to ground isolation. All models are certified to the IEC/EN/UL/CSA 60601-1, ANSI/AAMI ES 60601-1 and IEC/EN/UL/CSA 60950-1 safety standards. The QM series is also designed to meet IEC/EN61010-1 with CE marking for the Low Voltage, EMC and RoHS Directives. Earth leakage current is less than 300 µA, and complies with the EN61000-6-3:2007 and EN60601-1-2:2015 (curve B conducted and radiated) emission standards. The units also meet the EN60601-1-2 and EN61000-6-2 immunity standards and are designed and manufactured under the control of ISO9001 and ISO13485 (including risk management).
