1
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.
