Technology from ams that enables reliable NFC coupling in space-constrained devices, has been implemented in a system development board compatible with the STM32 family of microcontrollers from STMicroelectronics.
Optimated optical sensor can be used in wearables
Described as a further development of the optical sensor SFH 7050, the SFH 7060 from Osram Opto Semiconductors is designed to measure pulse rates and the oxygen saturation level of blood. The signal quality and low energy consumption enables it to be used in wearables such as smartwatches and fitness armbands. The new sensor is available at distributor Rutronik.
Small multi-GNSS module updates sports action
A family of products, beginning with this Multi Micro Hornet (ORG1510-MK) module combines a MediaTek chip with OriginGPS’ proprietary Noise Free Zone NFZ technology, to create small action sports cameras and wearable devices.
According to OriginGPS, it is the world’s smallest, fully integrated, multi-GNSS (GPS, Glonass and BeiDou) module. The low-power architecture supports an update rate of up to 10Hz and contains onboard flash, making it suitable for use as a GNSS component for devices that require small footprints, such as UAVs designed to follow action sports and other fast-moving activities, or wearable products.
The module contains the MediaTek MT3333 chip, claimed to support the fastest update position calculation rate, as well as an-onboard flash memory that does not erase when power is off. Standby and backup modes ensure it consumes very little power, says the company, and, in advanced applications, a periodic mode can turn the device on and off when in backup or standby.
The module measures just 10 x 10 x 6.1mm yet achieves rapid Time To First Fix of less than one second, accuracy within as little as 1m, and sensitivity at an industry leading -165dBm two constellations simultaneously, claims the company.
The Hornet family of GPS / GNSS antenna modules integrates a GNSS receiver and patch antenna in a single module. The ORG1510-MK is pin-to-pin compatibility with the Micro and Nano Hornet modules ensures a seamless migration from GPS to GNSS. Developers can simply connect the module to a power source on a single layer PCB to begin integrating it into designs.
