*A low-cost Arduino UNO controller board designed for domestic Arduino fans. Full compatible with Arduino UNO R3.
*Suitable for Arduino Beginners.
*Low-cost mian controller board. The main difference from the official one is that this board offers XBee socket and SPI directly-plugged interface, making the best of UART ports.
*For low-cost project, and Arduino communication module development.
*DFRduino Mega 2560 comes with plenty of IO ports, 54 digital ports, 16 analog ports, and 4 UARTs.
*Applicable to large projects that requires many sensors.
*Mega1280 has as many IO ports as Mega256, but comes with a smaller Flash. Besides, its price is lower than Mega2560.
*Suitable for low-cost projects requiring many sensors.
*Romeo V1 is specially designed for robot fans. It integrates motor driver, all sorts of communication ports, IO expansion port and so on.
*Extremely suitable for Arduino robot fans.
*The only difference between V1 and V2 is that Romeo V2 adopts ATmega32u4 chip, which provides 2 UARTs, convenient for wireless communication.
*For Arduino robot fans to build up projects with wireless communication.
*The first Arduino controller board that integrates Bluetooth 4.0, bring much more flexibliy and possibility for Android and IOS mobile development.
*For Android and IOS mobile App BLE developers.
*Integrated CC3000 wifi core and SD card function. Can store a large number of collected data. Compared with Wifi shield, wido is more lightweight and low-cost.
*For IoT developers.
