Not very exiting – just added the 3 extra 15uH coil options I mentioned earlier on the back. As mentioned these are added because I suspect I need them to separate 5V PSU to different high frequency modules. The issue, as we learned earlier is that these freuencies interact. The coils here simply let 5V through but stop higher frequencies – it cost me little to just add the space for these on the back side.
I have a weird package error on the 25 Mhz crystal that I need to check, otherwise this is ready to go.
Also starting to use “CCM” (Communication Central Module) as name on this because it contains Ethernet, GSM, GPRS, GPS, WIFI, Bluetooth, USB++
