Forum Post: RE: RF SOC based EVM from TI

Hi  JP Norair

Thank you very much for your reply,
We had some query regarding board selection which is mentioned below.

========================================================================
====                        Requirement                             ====
========================================================================

We need Dash 7 Standard TI MCU so by finding that on TI we found below MCU which full fills our requirements.

Dash 7 Standard TI MCU
----------------------

Standard: DASH7 (sub 1GHz)
Application: Asset Tracking
SoC: CC430F6137, CC430F5137

Below is the list of EVM options that we found from TI.

========================================================================
====                          Option - 1                            ====
========================================================================

CC430 Sub-GHz RF Experimenter’s Board
-------------------------------------

Kit includes 2 CC430-based development modules to enable a complete RF network
   - CC430F6137-based Base Board (MSP-EXP430F6137Rx)
   - CC430F5137-based Satellite Board (MSP-EXP430F5137Rx)

Our requirement
---------------
We need only one Base board and five Satellite boards for our project POC.
But in case of this Experimenter’s Board we have to buy both the boards.

========================================================================
====                         Option - 2                             ====
========================================================================

One more EVM we found on TI is "EM430F6137RF900"

========================================================================

1. In Option-1 EVM there is two option is available
   - with 433 Mhz
   - with 915 Mhz
   Which is more suitable with this application (Dash7 Mode 2)

2. In Option-2 EVM is only available with 915 Mhz does it works with our application ?
   We read some where that some of OpenTag API is not working with 915 Mhz is it true ?
   
Thanks,
