Xbee socket board

XBeeBreakout-01-L_i_ma.jpgWhile testing my setup, it often disturbed me that the Xbee Pro doesn't have a led somewhere to show it's powered up.Since I mount it onto a ply through an Xbee breakout board like the one on the picture, I just soldered a small red led between the VCC and GND. Now I know when it's powered ok without having to setup all Xbee transmission line.Of course, the led doesn't tell me if the Xbee is transmitting/receiving.

  • Thanks Reto and Thomas for your help. Time to get some ordering done.

    I doubt that the 900MHz XBee Pro board will take much over 300ma.

    You can use the Selmaware AppBee-SIP ( http://www.selmaware.com/appbee/index.htm ) XBee breakout board that has a TO220 3.3 v 1 A regulator on it.

    Just a thought.

  • I understand that my setup is not really meant for the lightest airframe. It's in a 2m high wing trainer with 5.5kg total flying weight.
  • I was hoping for something able to drop the ~11.1v straight down to the 3.3v @ around 1A on the same board as xbee to reduce component count but if I can't find anything then I'll certainly give those type of units a try. Thanks.
  • I power my Xbee directly from a DC/DC 5V/3.3V step down regulator board (I got 5 pieces from Ebay US). It's supporting 5A load and is itself powered from a separated 5V BEC (supporting 7A). The converter also powers the LS20031 GPS, an Arduino Pro Mini, and the FMA thermopile sensors (meant to run at 3.3V).
  • Has anyone come across a breakout board with a built in regulator such as the LD117v33 ? I ask because the Xbee pro specs suggest the unit can require up to 800mA max but the only breakout boards I can find with built in regulators cannot support anywhere near that load and I don't want to reduce the transmit power level . It would be nice to have the regulator mounted externally along with the Xbee to reduce the size of heat sink required.
  • To be honest, I really wonder what could go wrong when assembling the Sparkfun breakout?
  • Thanks for the comments Jordi. Since I already have 3.3V levels on my uC though, I was mainly curious about assembly differences. Given the negative comments on the sparkfun site regarding assembly: did you find the adafruit pcb to be less problematic, or the comments on sparkfun not to be relevant for you? You mentioned having 10 of these pcb's, so I assumed you were quite comfortable with assembly
  • Thanks Jordi for adding this comparison detail. I'm sure the Jordixbee breakout board will be a handy alterntive!

    Sparkfun red board, is nice if you want to interface easily to USB (i mean the computer), but it doesn't have power regular and TTL signal converter, and is a lot more expensive than Adafruit... And extra point of adatruit is that you can modify it to easily interface with ardupilot...
    Later i will develop my own XBee board, and open source it...
