CC2500 Breakout/BoosterPack

[RobG 1,890]

I could fit two more breakouts and one msp430, but that would exceed Seeed's specs (though I am sure with such a big order they will be flexible) and there might be other ideas.

Just one more with the G2553 on it would be fine I think, that would put you at the 5 board limit they set.

Small is beautiful. Man, you're really good at this! It looks great.

Not a breakout or anything, but a 43oh Keychain? I think it would look nice, and add +5 to geek cred.

Can you draw it and post it here?

:think:

Didn't we already hash that topic over?

:shifty:

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.

No. Bigger the chip we can afford, the better. In this case.. the 2553.

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?

[bluehash 1,578]

MTG,he'll know once you submit it.

[RobG 1,890]

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.

[cubeberg 540]

Hey guys - not sure if it could be used for this board - but I've got a 5% off coupon for iTead. It would actually make a difference in a large order like this. Let me know if you'd like to use it.

RobG,

I love that
