Just got an email from Digi-Key which states that the manufacturer of XT09-SI module marked it as “End of Life” and Digi-key will not sell them after March, 2016. Is it true? What is the replacement if so?
Its true and they have offered two replacements:
XTend v.B – A pin-compatible module in the same form-factor as the current XTend, which does
not require a redesign for existing XTend hardware designs and is over-the-air compatible with
XTend modules. Note there will be new part numbers and certification IDs (FCC ID, etc.) for
XBee-PRO XTC – A new XBee-PRO Surface Mount module with 1-Watt output power that is
over-the-air compatible with XTend modules. This allows customers to migrate to the SMT form
factor, which is ideal for those interested in reducing the size of their design while maintaining
OTA compatibility. Note there will be new part numbers and certification IDs for these modules.
