CC2500 Breakout/BoosterPack

Recommended Posts

After going back and forth all weekend on what jumpers to include, here's the "final" design.

The board includes:

1 Booster pack

2 G2xx3/CC2500 boards

2 breakout boards compatible with booster pack

1 breakout board with single row header

(I know this is one board too many, so if Seeed rejects it, I will remove single row breakout.)

 

Booster pack is designed to work with G2xx3 chips (is there any need for G2xx1/2 compatibility?)

 

Port mapping:

P1.1 - MISO (CC2500/SPI 2)

P1.2 - MOSI (CC2500/SPI 2)

P1.4 - SCLK (CC2500/SPI 2)

P1.5 - SCLK (CC2500/SPI 1, Memory)

P1.6 - MISO (CC2500/SPI 1, Memory)

P1.7 - MOSI (CC2500/SPI 1, Memory)

P2.0 - CS (CC2500/SPI 1)

P2.1 - GDO0 (CC2500/SPI 1)

P2.2 - GDO2 (CC2500/SPI 1)

P2.3 - GDO2 (CC2500/SPI 2) or Memory Hold

P2.4 - GDO0 (CC2500/SPI 2) or Memory CS

P2.5 - CS (CC2500/SPI 2)

 

When memory is not used, CS should be jumpered to Vcc, same with Hold.

 

What thickness are we going with?

1.0mm would be great for MCU boards, but might be too thin for the booster pack. 1.2mm should be perfect.

 

I will post the complete set of files later today.

Gotta say I love that design Rob.. The breakout with the pins in a single line is idea for breadboarding. Ribbon cables onto the 2x4 pins of the smaller breakouts was nice and the way I saw I would use the modules.. but that breadboard compatible one rocks for me.

 

So thanks bigtime.

Here are the files. They are final and I will touch them only if problems are found.

PLEASE review them, nothing like a second pair of eyes. I am not responsible for any losses if they turn out to be Geek Coasters :)

 

Gerber files were created from cc2500-final.brd. There's no corresponding sch because MCU board layout was copied.

You can view them online at circuitpeople.com.

 

BTW, I just realized that G2xx1/2 can be used if you bit bang and jump CS (to P1.0 or P1.3 for example.)

If this does not pass with seeedstudio, do you have a alternative ready?

Make them an offer they can't refuse :)

If needed, I can make an alternate fairly quickly. I will just put 2 breakout boards head to head without any visible cut line and then join them so they appear as a single board. :D
