CC1101 BoosterPack


Recommended Posts

After reading some of the Launchpad shield discussion here and while I'm waiting around for my Chronos, I figured I would design a nice Arduino-style "shield" to go on the Launchpad that uses the CC1100 sub-1GHz RF chips to interface with the Chronos. The CC1100 only uses SPI, so the shield should be stackable (in theory).

 

Here's an initial schematic I whipped up-

Edit: Gah, I screwed up with the left side headers. No biggie.

I'm not trying to thwart your plans, but I found a link to this webpage when looking up info on the g2553.   I can't post links since I'm too new, but if you google the part number "430boost-cc110l"

Possibly the final version of the board, unless I find some glaring issues: I dropped the Fraunchpad idea because there was no good way to attach it to the board...

Cool!. I have a few of these chips and was thinking about building a prototype. I'd gladly buy a few boards. They should be pretty easy to build with minimal parts. The official modules from TI are overpriced.

 

I have to order in a batch of 10 if I want these professionally made. I'd be willing to send people some if they pay a few bucks for the board/shipping. The CC1101 can be gotten as a sample from TI.

 

It turns out there's a lot of room left over after putting the chip on... Maybe I'll put on an LCD or some buttons as well.

that is a kind offer, but I am looking for/designing a mount for the flex module from LS Research, or similairily the MChip module. Have a look at the deals section, you may want to get yourself a demo of the flex for the price of shipping.

Found some time to figure out the RF connectors on the Fraunchpad. I couldn't make any sense of the RF1/RF2 connectors, so I ended up using the ezRF (RF3) connector, which isn't broken out on the board.

 

For reference:

ezRF on the Fraunchpad:

RFPWR - GND

P1.0 - P2.0

P1.1 - P2.6 (eUSCI_A1 SOMI / SDO)

P1.2 - P2.5 (eUSCI_A1 SIMO / SDI)

P2.3 (eUSCI_A1 slave /cs) - P2.7

GND - P4.0

P2.4 (eUSCI_A1 clock) - P4.1

P2.2 - P1.7

P1.6 - P1.3

 

Fraunchpad: http://www.ti.com/tool/msp-exp430fr5739 ... 57xx-pr-tf

Datasheet: http://www.ti.com/lit/ug/slau343/slau343.pdf

 

The Fraunchpad page says it has 1 USCI block, which I'm assuming means it has eUSCI_A0 and eUSCI_A1. Still new to this stuff, so not quite sure.
