The CT-UNO combines the simplicity of the UNO’s Optiboot bootloader (which load program faster), the stability of the FTDI and the R3 shield compatibility of the latest Arduino UNO R3.
Besides, we know many are using Android phone which comes with USB micro-B cable (power bank also require micro-B to charge), therefore, to lower down the cost needed for customer to get started, we populate the USB micro-B socket for USB connection! Program can be loaded from Arduino UNO by utilizing your Android phone USB cable. Select “Arduino UNO” from the board and choose the correct COM port, you are ready to upload the code.
CT-UNO has all the amazing features Arduino UNO offer. 14 Digital I/O pins with 6 PWM pins, 6 Analog inputs, UART, SPI, external interrupts, not to forget the I2C too. The SDA, SCL and IOREF pins which being broken out on UNO R3 are on CT-UNO too. We has also populated the ISP header pins (SPI and power). With this, CT-UNO will be compatible with all Arduino UNO’s shield.
