    v13 v14  
    114114This is a 40-pin 2mm dual-inline connector which mates !BiBo’s control signals, +3.3 VDC power and ground to !WiBo.

    142142AUX_DAC_A can control the PLL CP output of the MAX2829 to effect faster lock times.  This might be done with a look up chart or an available ADC could be used to implement a Wiener or Kalman filter.

    144 Filters F70, 71, 72 and 73 are receive filters (Murata LFB or LFD or TDK DEA type) intended to channel select either 2.4 or 5.6 GHz. Similarly F60 and F61 can be used used to limit spurious output of the TX.  By observation, the TX spurs are very far down and do not need filtering.  By design default, none of these filters are populated on WiBo (they are hard to get in quantities less than 10,000!).
