RF Daughter Card Connect

Ivan Ivanov5

I want to connect a sensor supply to the connector of expansion cards. What tension and current I can receive there? Where these connectors are described in documentation? Whether the additional stabilizator is necessary?

Which development board(s) you are talking about?

I am limited in connection by RF1 and RF2 connectors of the experimental board. It isn't possible to find their characteristic to select to itself the necessary 2 outputs for my sensor (ground and power). Can you help me ? I looked for information in board and microcontroller documentation. I entered into search the words signed at pinches of these connectors on the diagram of a board. The power supply range of my sensor is from 2.5V
to 5.5V (there is a built-in stabilizator) and supply current 35-60 μA. I read this docs http://www.ti.com/tool/msp-exp430fg4618. Thank you.

In page you mention there's user guide for download, http://www.ti.com/lit/ug/slau213a/slau213a.pdf

Check Page 18, schematics. Even pins of RF2 connector are GND, pins 7 and 9 are VCC which most probably will be able to supply 50 mA or even more.
