USB (Programming with ATmega 8), ICSP (programming), SPI, I2C and USARTĪrduino Mega – Advanced Features Arduino MegaĪrduino Mega 2560 is also packed with additional features like Analog Comparator, External Interrupt & Software Interrupt, Power Saving Mode, Inbuilt Temperature Sensor, RTC and more. Arduino Mega 2560 SpecificationsĪrduino Mega – Basic Features Arduino Mega Due to the many numbers of pins, it is not usually used for common projects but you can find them in much more complex ones like Radon detectors, 3D printers, temperature sensing, IOT applications, real-time data monitoring applications etc. The Arduino Mega 2560 is a replacement of the old Arduino Mega, and so in general reference, it will be called without the ‘2560’ extension.
It supports ICSP as well as USB microcontroller programming with PC. It is also compatible with the different type of boards like high-level signal (5V) or low-level signal (3.3V) with I/O ref pin.īrownout and watchdog help to make the system more reliable and robust. With large FLASH memory and SRAM, this board can handle large system program with ease. Other features include JTAG support for programming, debugging and troubleshooting. It has more than 5 pins for Vcc and Gnd to connect other devices to Arduino Mega. Secondly, it has inbuilt RTC and other features like analog comparator, advanced timer, interrupt for controller wakeup mechanism to save more power and fast speed with 16 Mhz crystal clock to get 16 MIBS. First feature is the large I/O system design with inbuilt 16 analog transducers and 54 digital transducers that supports with USART and other communication modes. Despite the name, the board does not appears to be designed by Wemos, since there’s no mention of it on their Wiki nor Aliexpress store.When cheaper boards are available, why go with Arduino Mega? The main reason behind this is the additional features that are inbuilt with this board. While searching for other sellers for the board, I also came across Wemos “TTGo” D1 R32 going for just over $10 on Banggood, and basically the same specifications as ESPDUINO-32, except it replaces the USB type B receptacle with a micro USB port. You’ll find links to documentation in Smartduino github account. Note that if you have shields using the Analog input they may not work properly since there’s only one input supporting up to 3.2V, as Arduino UNO board support 6 analog inputs up to 5V. The board can be programmed with the Arduino IDE selecting ESP 32 Dev Module board. Power Supply – 5 to 12V input via DC jack or Vin pin.Expansion – Arduino UNO headers with SPI, I2C, digital I/Os, 1x analog input up to 3.2V, 5V, GND.

Wireless Module – ESP-WROOM-32 based on Espressif ESP32 dual core Tensilica LX6 processor with 802.11 b/g/n WiFi and Bluetooth 4.2 LE.We’ve previously seen Noduino Quantum board sold for 99 RMB on Taobao, and $25.90 on AnalogLamb, but doit.am has designed a cheaper model called ESPDUINO-32 that supports shields compatible with Arduino UNO, and sold for $13.73 on DealExtreme.
The compact ESP32 NodeMCU like board are great for many project, but in case you plan to leverage your existing Arduino shield, it’s more convenient to have a compatible board.
