Pulse Sensor is a well-designed plug-and-play heart-rate sensor for Arduino. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heartrate data into their projects. The sensor clips onto a fingertip or earlobe and plugs right into Arduino with some jumper cables. It also includes an open-source monitoring app that graphs your pulse in real time.

The Broadcom? BCM43341 single–chip quad–radio device provides the highest level of integration for a mobile or handheld wireless system, with integrated dual band (2.4 GHz / 5 GHz) IEEE 802.11 a/b/g and single–stream IEEE 802.11n MAC/baseband/radio, Bluetooth 4.0, and FM radio receiver. It also integrates a low power NFC controller based on the BCM2079X, an NFC standards–compliant standalone solution. The BCM43341 includes integrated power amplifiers and LNAs for the 2.4 GHz and 5 GHz WLAN bands, and an integrated 2.4 GHz T/R switch. This greatly reduces the external part count, PCB footprint, and cost of the solution. Using advanced design techniques and process technology to reduce active and idle power, the BCM43341 is designed to address the needs of mobile devices that require minimal power consumption and compact size. It includes a power management unit which simplifies the system power topology and allows for operation directly from a mobile platform battery while maximizing battery life

This document describes the Broadcom? BCM943xxxWCDx_EVB WICED evaluation board and associated components. The BCM94343xxxWCDx_EVB is comprised of a module soldered onto an evaluation board. While this document will focus on the BCM94343WWCD1_1 module as the core example, the content is applicable to modules that use the following three variants: ? BCM43364 ? BCM4343W ? BCM43438 A single evaluation board is used for each of these variant modules and has the part number BCM9WCD9EVAL1. The BCM94343WWCD1_1 is a chip-on-board module that provides the highest level of integration of the BCM4343W with an STMicroelectronics? STM32F411 microcontroller. This combination is uniquely suited for Internet-of-Things (IoT) applications in the industrial and medical sensor, home appliance, and embedded audio markets. The purpose of this document is to support hardware designers from our various OEM/ODM module partners who are designing their own BCM943xxx-based module for compatibility with the Broadcom BCM9WCD9EVAL1 evaluation board. The document includes, among other things, module pinouts, signal descriptions, example schematics, layout, RF considerations, and so forth.
