Atwo-pin power and communications connection between earbuds and cradle has been developed by ams. The company introduces POW:COM, an interface technology which enables power and communication between a true wireless earbud and a charging cradle over a two-wire connection. A true wireless earbud previously required as many as six pins to provide both power transfer and communication between the charging cradle and the earbud, compromising the mechanical design of a small form factor that fits comfortably in the user’s ear.

Wireless charging kit can lead to reduced form factor for IoT and wearable devices
Compact chargers for IoT and wearable devices can be reduced in size, using the STEval-ISB045V1 wireless battery-charger development kit, says the company. It lets users quickly build compact chargers, up to 2.5W, with a space-saving 20mm-diameter coil, for charging small smartwatches, sports gear, or healthcare equipment.
Microchip’s Bluetooth SoC combines Sony’s LDAC technology for audio devices
Today’s consumers expect Bluetooth audio devices to create an immersive and uninterrupted listening experience. Bluetooth audio designs, however, can be limited by the bit depth and frequency rate of existing codecs, the communication and compression technology used to send audio over the air. To bridge this divide, Microchip has developed a certified, Bluetooth 5-compliant system on chip (SoC) with Sony’s LDAC audio codec technology. Sony’s LDAC is considered the highest-quality audio codec available, reports Microchip. It transmits up to 990kbits per second data throughput, which is three times higher than the standard Bluetooth Sub-band Codec (SBC), and maintains frequency and bit depth of up to 96kHz/24-bit. The high compression and reproduction efficiency enables high-resolution audio listening experiences for Bluetooth audio devices, adds the company.
Fast eye tracking technology provides ergonomic design for AR/VR
