CN15
- 20 pin 2mm header, XMOS JTAG programming header. Schematic page 31. This can connect to an XMOS xTAG3 programming adapter with a 0.1" 20 pin to 2mm 20 pin cable. Wires are crossed, that is 2mm pin 1 goes to 0.1" pin2 and the 2mm pin 2 goes to the 0.1" pin1, etc for the other pins. Note: this is only needed if custom XMOS audio processing code is to be developed. 3.3 volt levels.
Was ist XMOS?
CN14
- 10 pins, Digital microphone 3 & 4 inputs. Schematic page 31. Contains two stereo I2S audio input channels. 3.3 volt levels. There are an 3.072 MHz bitclock and 48 KHz left/right clock on this, along with a data input.

CN16
- USB 2.0 (marked WEBCAM). Schematic page 33. Can be used as a general purpose USB 2.0 port. Will work with an external USB hub also to get more ports.
Ok, sehr interessant ist CN16, falls man doch mehr USB-Ports (2.0) benötigt.
