Arduino Bluno Mega 2560 BLE is designed for makers, educators, developers. Arduino Bluno Mega 2560 BLE has helped tons of ideas become prototypes. Today, please allow m to introduce a new member in this flourishing BLE family: BLUNO MEGA.\u003cbr\u003e\u003cbr\u003eBluno Mega2560 inherits the numerous ports and the abundant resources of Mega series, and adds Bluetooth 4.0 wireless communication function. It has 54 digital I\/O (input\/output) ports (15 of which can be used as PWM output), 16 analog input and 4 UART (hardware serial ports), and uses 16 MHz imported crystal oscillators. So, if you are feeling a lack of ports or desire more RAM, flash or EEPROM memories, here is the answer. With it's bootloader it can directly download programs via USB without any other external flashing devices. Mega 2560 has twice as big memory space as 1280 and 256k flash memory. Bluno Mega2560 has two options for the power supply system, including USB power supply or external power supply. The power supply will be automatically switched.

It works by simulating a UART device beneath the surface, sending ASCII data back and forth between the devices, letting you decide what data to send and what to do with it on either end of the connection.\u003c\/p\u003e\n\u003cp\u003eUnlike classic Bluetooth, BLE has no big contracts to sign and no major hoops that you have to jump through to create iOS peripherals that you can legally design and distribute in the App Store, which makes it a great choice compared to classic Bluetooth which had (and still has) a lot of restrictions around it on the iOS platform.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eAnd now that Android also officially supports Bluetooth Low Energy (as of Android 4.3), it's also -- finally! -- a universal communication channel covering the main mobile operating systems people are using today.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003ePlease note! We still manufacture and support the nRF8001 Bluefruit module sold here, but we really recommend going with the fresh new Bluefruit LE nRF51822 based modules, they're much more powerful and thus need less code on the Arduino side, have a lot more capability and flexibility so you can do more, require fewer pins, are overall smaller, can be updated with new firmware and are FCC\/CE approved! They come in both UART and SPI interface type (both have same functionality, one just uses serial, one uses SPI\u003c\/p\u003e\n\u003cp\u003eWe can get you started super fast with this BLE module which can act like an 'every day' UART data link (with an RX and TX characteristic). Send and receive data up to 10 meters away, from your Arduino to an iOS device. We've even made it easy to get started with our very own BLE connect app that has a \"serial console\" for sending\/receiving data and also an 'arduino pin i\/o control station\" to let you set pins on your Arduino to inputs or outputs, high or low logic or even PWM output, as well as read button presses and analog inputs. You can start prototyping your accessory and then use our open source Objective C code to base your new app on!\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe nRF8001 is nice in that it is just a BLE 'peripheral' (client) front-end, so you can use any micrcontroller with SPI to drive it.

Heck yeah! With BLE now included in modern smart phones and tablets, its fun to add wireless connectivity. So what you really need is the new Adafruit Bluefruit LE SPI Friend!The Bluefruit LE SPI Friend makes it easy to add Bluetooth Low Energy connectivity to anything with 4 or 5 GPIO pins. With SPI, you don't have to worry about baud rates, flow control, or giving up a hardware UART port. Connect to your Arduino or other microcontroller using the common four-pin SPI interface (MISO, MOSI, SCK and CS) plus a 5th GPIO pin for interrupts (to let the Arduino know when data or a response is ready).This multi-function module can do quite a lot! For most people, they'll be very happy to use the standard Nordic UART RX\/TX connection profile. In this profile, the Bluefruit acts as a data pipe, that can 'transparently' transmit back and forth from your iOS or Android device.

The new BLE 4.0 wireless gamepad V2.0 produced by DFROBOT can meet all your requirements. Based on TI CC2540 Bluetooth chip design, it is specially designed for DIY players and does not need programming. This gamepad is using hardware scanning structure, high respond to speed, and supports one keyboard toggle between central and peripheral roles. Under central device mode, it can be connected to any DFRobot BLE device and achieve remote control. While under peripheral device mode, the gamepad can be used as an HID keyboard-mouse device for pc. This product also supports multi-button recognition, each button has pressed and released stage, which is more friendly for remote control.\n \u003c\/p\u003e\n\n \u003cp\u003e\n Based on the previous version, Bluetooth Gamepad V2.0 not only improved on hardware but also made the connection more stable.
