Cambridge, UK Arcom has released a versatile PC/104 baseboard suitable for adding cellular wireless communications to any embedded Machine-to-Machine (M2M) system. The WEB-Telemetry (Wireless-Embedded-Baseboard for telemetry) includes sites to locate several leading iDEN and GPRS/GSM cellular modems from Motorola, Sony Ericsson and Siemens. The board also serves as a wide input (10 to 30 V) regulated power supply for the PC/104 processor board, as well as providing an integrated Trimble GPS receiver module and digital inputs for status signals. PSU, a modem carrier and a GPS receiver card are combined into a single 155 x 100mm board with I/O connectors conveniently located along one edge of the board. The onboard power supply can supply up to 2.5 A at 5 V, 2.5 A at 3.6 V and optionally, 250 mA at ±12 V. The WEB-Telemetry can be fitted with GPRS/GSM modems from Sony Ericsson (GM47/48) and Siemens (MC35i), as well as the Motorola iO200 and iO1500 modems used for the Nextel iDEN network. The iO200 has been designed with integrated GPS functionality and offers a low cost solution for M2M applications using the Nextel data network. The WEB-Telemetry provides the matching connectors, power supplies and where appropriate, the SIM card (Subscriber Identity Module) carrier for plug-n-go operation. The board can be fitted with a low power Trimble LassenSQ GPS receiver to provide positional data and an accurate 1 pulse per second synchronized to an atomic clock (UTC).

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
