This optical heart-rate module reference design incorporates red and infrared LEDs, a sensor, power subsystem, and logic level translation. Measuring 13mm x 13mm, this tiny, low-power board can be placed on a finger or earlobe to accurately detect heart rate and SpO2 via personal wearable devices. The module works with both Arduino and ARM mbed […]

Linear Technology introduces the LTM4647, a 30A step-down µModule (power module) regulator. The LTM4647 includes the inductor, MOSFET, DC/DC controller and supporting components in a 9mm x 15mm x 5.01mm BGA package. The device’s conversion efficiency from 12VIN to 1VOUT at 30A is 87%, when delivering a full 30A continuously without a heat sink or […]
Linear Technology Corporation introduces the LTM2885, an isolated RS485 µModule® transceiver for guarding against large ground-to-ground differentials. Many industrial, utility, medical, military, and intrinsic safety applications require isolation components with increased voltage and spatial separation for human safety. The LTM2885 provides 6500VRMS reinforced isolation between the logic level interface and the transceiver bus pins, far […]

Wurth Electronics Midcom announces the new series of isolated buck transformers for Maxim Integrated’s MAX17681 converter. These pick and placeable transformers, built on self-shielding packages, have small form factor and losses. The high-efficiency MAX17681 converter eliminates the need for optocoupler feedback circuits and can deliver up to 3W of output power. The application of these […]
Silicon Labs has introduced the industry’s smallest Bluetooth® low energy system-in-package (SiP) module with a built-in chip antenna, offering a complete, cost-effective connectivity solution with no compromises in performance. Available in a tiny 6.5 mm x 6.5 mm package, the BGM12x Blue Gecko SiP module enables developers to miniaturize IoT designs by minimizing the PCB […]
