No hay artículos en el carro Introducción:
keyestudio Mega es una placa de desarrollo (utilizada con oscilador de vidrio de 16 MHz) de microcontrolador. Hay 54 interfaces digitales de E/S (entrada/salida) (de las cuales 15 son salidas PWM), 16 entradas analógicas y 4 UART (puertos de hardwareeserial). Con su gestor de arranque, el programa se puede descargar directamente con USB y no necesita utilizar otro programador externo. Se puede alimentar directamente por USB o adaptador de CA a CC y batería.
2Diseño de fuente de alimentación:
Hay dos opciones (fuente de alimentación directa a través de USB o fuente de alimentación externa) para el sistema de alimentación de Mega, y se pueden cambiar automáticamente.
La fuente de alimentación externa puede ser adaptador de CA a CC o batería.
El rango de voltaje de esta placa de control es de 6 V ~ 12 V, pero si el voltaje suministrado es superior a 12 V, es probable que el dispositivo estabilizador de voltaje se sobrecalentará y la protección contra sobrecalentamiento y dañará MEGA.
Por lo tanto, sugerimos que la fuente de alimentación sea de 6,5 ~ 12 V en funcionamiento y la fuente recomendada es de 7,5 o 9 V.
Especificaciones:
Microcontrolador: ATmega!2560.
Voltaje de funcionamiento: 5 V.
entrada de voltaje (recomendado): 7-12 V.
Pasadores de E/S digitales 54 (de los cuales 15 proporcionan salida PWM)
Pinzas de entrada analógicas: 16.
Corriente CC por pin de E/S: 20 mA.
Corriente CC para pin de 3,3 V: 50 mA.
256 KB de los cuales 8 KB utilizados por el gestor de arranque
SRAM: 8 KB
EEPROM: 4 KB.
Velocidad de reloj: 16 MHz.
El embalaje original incluye:
1 placa KEYESTUDIO Mega R3.
1 cable USB.

Excellent Arduino mega, easy to setup and connect to Arduino IDE, everything went great! Just like an original Arduino. This is the second time I bought from this Brand

I have several Uno's and Nano's but I needed an Arduino Mega to follow along with one of Ben Eater's (beneater dot net) projects and this was the one he used. It comes with instructions on downloading and installing a driver on Windows machines. I have a Mac so didn't need that but I did need to update my Arduino AVR Boards in the Board Manager tool for it to show up correctly as an "Arduino Mega or Mega 2560".I modified the standard Blink example just to make sure I could write to the Mega and everything went fine. I don't anticipate any issues. Now that I have it, I'll have fun looking for / designing other projects that utilize the additional I/O pins.

Worked perfectly out of the box with the Arduino IDE on OS X.Using this Mega compatible to monitor 4 independent rotary encoders with push buttons, control a Neopixel Ring (volume indicator) and communicate via USB serial to a Raspberry Pi on an antique radio modernization DIY project.Highly recommended.Will be buying more for future projects.

Initial reaction: - it was love at first sight. The yellow and black "Killer Bee" appearance sold me right away. I watched a few youtube videos and other online reviews and decided to buy one of these and a UNO R3 as well. The only downside, this board didn't qualify for the 1 day Free Shipping that I had hoped for.Indeed, the wait was longer than that.....and no fault of either Amazon or Keyestudio. This particular package got routed to the wrong Postal SubStation and took a total of 4 agonizingly long days to arrive in my mailbox.In the meantime, I had received the Keyestudio UNO R3 that I had ordered and I was impressed by the quality of construction and the clarity of the printing on the PCB. Based on that board and tired of waiting, I ordered another Mega 2560 in the hope that one would eventually arrive.Anyway, it was worth the wait. Very little to nitpick about on this board. It looks sharp and the color scheme helps to make it jump out from the usual clutter of my desk. I powered it up, checked the board info on the sketch menu and ran a couple of projects without any issues.This board does come with a short and thick blue cable to connect to a USB port. As time goes by, I'll likely buy a few more of these boards.

1) Mounting hole dimensions is not the same as the original Arduino Mega 25602) 3.3v pin on the board outputs 5V instead of 3.3V
