   In the previous image can be seen which pins are for the serial adapter and which ones are power
   pins. All the other pins are used for ACI/SPI connection. For further details about how connections

  Connections are almost the same for most of the elements. The YRPBRL78G13 board and the 
  nRF8001/nRF24L01+ have exactly the same connections. For this reason its images are not shown again.
  A closer look of the external regulator connections can be seen in the next image.

  On the left side comes the 5V input from the YRPBRL78G13 board, and on the right side is the 3.3V output
  that goes to the nRF8001/nRF24L01+.

  On the left side can be seen the ACI/SPI connection and as the image shows not all the ACI/SPI pins 
  are used. On the right side is power pins connection coming from the Arduino.
