Wi-Fi and low power radio as plug-ins for Raspberry Pi RS Components has added two wireless connectivity options to its portfolio of products based on the Raspberry Pi computer. The new modules are built using Wi-Fi and low power radio technology respectively and deliver wireless interface capability for mobile applications. The first module offers high-speed Wi-Fi functionality compliant with the IEEE802.11b/ g/n wireless protocol via a tiny adapter that plugs into the USB port on the Raspberry Pi. The adapter supports transmission rates of up to 150Mbps. The smart adapter adjusts the transmission output according to the distance and CPU offload to achieve a reduction in power consumption of between 20% and 50%. RS Components www.rs-components.com Instant global positioning from a 22x22x8mm GPS antenna module New to the Alpha Micro product portfolio is the u-blox PAM- 7Q GPS/QZSS antenna module measuring 22x22x8mm. The device integrates a satellite receiver IC plus all passives and a pre-tuned GPS antenna in one single compact package. Designed for applications such as portable, covert tracking, asset-tracking, animal and child tracking devices, this new module combines low-power consumption with highsensitivity, sophisticated noise suppression and I2C / UART interfaces, making the integration of global positioning as simple as possible. PAM-7Q can easily be integrated into pre-existing designs or soldered with a pin-header to a customized PCB. The 18x18mm patch antenna is designed for optimal antenna performance independent of orientation. Alpha Micro http://alphamicro.net STM32-based Nucleo development boards compatible with Arduino Mouser Electronics is now stocking and shipping the new Nucleo Development Boards from STMicroelectronics, for anyone to get started with ST’s STM32 product families. Besides the usual assortment of push buttons, LEDs, and a USB debug interface, Nucleo boards feature two unique sets of expansion headers. The first set of expansion headers sit on the outside edges of the board, and are standard headers on all Nucleo boards. The second set of expansion headers are nestled inside the first set and are Arduino shield compatible. Mouser Electronics www.mouser.com Multi-touch PCT technology takes up to 40 contact points MSC Technologies now stocks Zytronic’s Multi-touch Projected Capacitive Technology (MPCT), supporting up to 40 independent contact points to be analysed simultaneously on displays of up to 85“. This multi-touch technology is based on Zytronic’s ZXY200 and forthcoming ZXY300 touch controllers and a robust scalable touch sensor. It uses a matrix of copper electrodes of 10 μm in diameter which are located in impact and scratch-proof glass laminate of several millimeter thickness. A palm rejection function differentiates between deliberate and erroneous contact with the touch panel. The sensor even works when wet, dirty or touched with gloves. Users can also access the controller firmware and adjust the sensitivity themselves. This allows the sensor to be precisely adjusted to the respective requirements of the system design. MSC Technologies www.msc-technologies.eu 4.8” TFT display packs 720x1280 pixels with wide viewing angles Japanese manufacturer of TFT modules Ortustech Technology is offering a wide product range of small and medium sized TFTs from 5.1 cm (2.0”) up to 17.78 cm (7.0”) screen sizes distributed by Data Modul. The 4.8” TFT COM43H4M87ULC unit in particular boasts a very high resolution of 720x1280 dots, supporting a very sharp and crystal clear image. The pixel structure is not visible for the human eye, whilst the viewing angles of L/R/U/D 80°/80°/80°/80° make the TFT readable from all directions. The blanview technology also makes the TFT readable under sunlight conditions. The unit measures 63.7x115.6mm for a thickness of only 1.6 mm. Data Modul www.data-modul.com M2M module offers cost-effective migration from 2G to 3G From distributor MSC, the Quectel UC15 3G-Module provides cost-effective migration from 2G to 3G. The module is UMTS/HSDPA-capable and is pin-compatible to the same company’s M10- and M12-GPRS Class 12-Modules. Covering bands from 900 to 2100 MHz for multiband-W-CDMA and 850/1900-MHz quad-band-GSM, the module, measuring 29 x 29 mm, is downwards compatible to EDGE and GPRS with Multi-Slot Class 12. UC15 has power consumption of 3.5 mA in sleep mode, and 520 mA maximum in UMTS mode. Interfaces include USB, UART, PCM as well as two analogue I/Os and ADC-channels. The maximum download speed is 3.6 MBit/ sec and the transfer rate at upload is 384 kbit/sec.
