Microcontroller with bluetooth low energy.

The max32666 dual core microcontroller from maxim integrated products integrates bluetooth ble 5 2 wireless connectivity for internet of things iot designs aimed at the iot space maxim integrated products has launched a dual arm cortex m4 mcu with floating point unit fpu and bluetooth low energy 5 2 ble 5 2. Bluetooth 5 2x speed feature requires a hardware update so the older devices chips modules does not support it. The qn9090 and qn9090t called qn9090 throughout this document are ultra low power high performance arm cortex m4 based wireless microcontrollers supporting bluetooth low energy 5 0 to facilitate the development of bluetooth low energy applications. Bluetooth low energy is the hottest new low power 2 4ghz spectrum wireless protocol.

The blend ble microcontroller blends arduino with bluetooth 4 0 low energy aka ble or bluetooth smart into a single board. In this architecture the bluetooth low energy microcontroller acts as a co processor which takes on the responsibility of bluetooth connectivity maintenance. With our bluetooth low energy modules there s no need to be an rf expert or navigate the costly and time consuming certification process. So what you really need is the new adafruit bluefruit le micro it s an atmega32u4 chip same as used as in the adafruit flora or arduino leonardo plus our spi bluefruit le friend in one.

Blend is 100 compatible with sketches and shields that work with arduino leonardo. It enables robust ble master or slave nodes to be built with very low total bill of material costs. Between the dual cores there is a data bus. Disadvantages of bluetooth low energy.

In order to achieve reliable communication in the 2 4 ghz frequency band it employs a robust frequency hopping spread spectrum method that transmits data over 40 channels. About bluetooth low energy bluetooth low energy le is designed for very low power operation and is optimized to short burst data transmission. In order to achieve the higher throughput bluetooth low energy devices communicating with each other need to support the new le 2m phy. These modules come with global certification preprogrammed firmware and a simple ascii interface for ease of use.

The cc2540 is a cost effective low power true system on chip soc for bluetooth low energy applications.
