TWI Interface(SDA, SCL) x 2 [(20,21),(70,71)] CAN Interface (CANRX , CANTX) x2 SSC Interface (RF, RD, RK, TD, TK, TF) UART (Universal Asynchronous Receiver Transmitter) Interface can be used to program PRO MINI SPI (Serial Peripheral Interface) Interface ban be used to program ...
Unlike my understanding of Sparkfun's write-up for the Pro Mini, it works fine to upload programs with just an FTDI cable, don't need the special FTDI adaptor. It would also be helpful to explain how to install the pull-up resistors onto the solder pads provided for SDA and SCL. Can...

(3.3V 8mHz version) paired up with the MPU6050 Gyro + Accelerometer motion sensor to determine the drone's orientation in flight. We'll mount and connect it to the Arduino using only a 2-pin header for two-wire (SDA & SCL - I2C) communication and a couple more wires for power. As ...

SDA 19 5 28 PC5 SCL Leonardo The Leonardo introduced the ATmega32U4 processor, which contains a built-in USB interface and enhanced functionality. This simplified the PCB layout, as can be seen in Figure 4-19. Also, note that the Leonardo uses a mini-USB connector instead of the full-siz...
SDA –(Pin 4) – The I2C Data line. Note the similar pinout to the Arduino Uno, which also used A4 as SDA. SCL –(Pin 5) – The I2C Clock line. Again this is the same pinout as the Uno. TX –(Pin 6) – The UART Transmit line. RX –(Pin 7 ) – The UART Receive line....
