All typical specifications are measured at 25°C.

2

Absolute maximum stress rated voltage for VCC is -0.3 to 3.6. It is recommended that a bulk decoupling capacitor (47 uF

tantalum rated at 6.3volts) be located close to the VCC pin 21 of the SM200 connector on host board.

3

2.4Ghz transceiver current only. Does not include current required to run CPU.
