Being a "new guy" with the Radioberry board, can I use a N2ADR bandpass/amp board with it?  If so, what is involved?
Thanks in advance,
Jim W0CHL

N2ADR board is in the list.

OK!  I have a N2ADR board in my hand.  I did not understand what is needed to get the N2ADR board to work.  Can someone give a "step by step" procedure? Perhaps a schematic showing the connections?  I'm confused about the hookup and software needed. 
Thanks,
Jim W0CHL

I'm still at a loss, trying to find out more on making a N2ADR board work with a Radioberry. The link that was pointed out tells me the I2C address was 0x20 but that is all.  Could someone give me more information or tell me who has done this modification?
Thanks, Jim W0CHL

Just connect pin 17 and pin 18 to the i2c bus of the N2ADR board (and gnd of course).

The firmware does control the N2ADR i2chip.

I do not have such board... never tried it but it should work.

Have fun

Hello,

I've mated an N2ADR filter board to my Radioberry SDR.

I used the FPGA SDA/SCL, pins 15 & 16 of CN301 since I am using the Juice board.
It works.

Also, I needed to add 10k pull-up resistors to R303 & R304 to the SDA/SCL to get it working properly.

Hi Rick,

Tnx for confirming that the control of the N2ADR board using the juice gateware is working.

Your welcome.

BTW, this is my Radioberry with 10 Watt QRP-PA 2008 and N2ADR board in a Hermes-Lite case:
