Hello,

I would like to use the Xbee S1 board to read an analog voltage (so using the ADC) and send it out to a board (STM32) through the USART interface. All would be done using one Xbee module

It is possible?

Yes it is. See [http://knowledge.digi.com/articles/Knowledge\_Base\_Article/Analog-to-Digital-Conversion-on-the-XBee-802-15-4/?q=xbee+ADC&amp;l=en\_US&amp;fs=Search&amp;pn=1](http://knowledge.digi.com/articles/Knowledge_Base_Article/Analog-to-Digital-Conversion-on-the-XBee-802-15-4/?q=xbee+ADC&amp;l=en_US&amp;fs=Search&amp;pn=1) as well as the ADC section of the product manual.
