  • The MOD-ZIGBEE-PIR I received lacks 4 pins at the UEXT connector. Did you send me a faulty device?
  • Your MOD-ZIGBEE-PIR is fine. In later revisions pins 7, 8, 9, and 10 of the UEXT connector were removed on purpose to avoid confusion and to lower the chances of possible hardware incompatibilities.
  • I receive funny characters on the terminal using MOD-ZIGBEE. What should I do?
  • Set the terminal baud to 19200
  • What is the difference between MOD-ZIGBEE, MOD-ZIGBEE-UEXT and MOD-ZIGBEE-PIR
  • MOD-ZIGBEE is the base ZIGBEE module; the MOD-ZIGBEE-UEXT has UEXT which allows easier connection to Olimex host boards; the MOD-ZIGBEE-PIR has UEXT and also a PIR (passive infra red) sensor
