Datasheet
Module Specification Notes:
Note 4
The BT900 module comes loaded with smartBASIC runtime engine firmware but does not come loaded with
any smartBASIC application script (as that is dependent on customer-end application or use). Laird provides
many sample smartBASIC application scripts covering the services listed. Additional BLE services are being
added every quarter.
Note 5 Deep sleep consumes 2.7uA of power when the BT900 internal radio chip 32.768kHz is used. The smartBASIC
runtime engine firmware has SIO (DIO default function) input pins that are PULL-UP enabled by default. You
may disable the internal PULL_UP through a smartBASIC application script.
Note 6 1.8V operation not supported in current smartBASIC runtime engine FW. 3.3V operation only (2.8V-3.6V).
