3 Application Interface
3.1 Power Supply
BlueMod+SR require a power supply with the following characteristics:
Typical: 3,3V
DC
, min.: 2,5V
DC
, max.: 3.6V
DC
, low noise (≤ 10mV
rms
), > 80mA peak
For optimal performance a stable supply is recommended. If a regulator is to be used, it should be
a fast linear regulator placed as close as possible to the VSUP pins (E-6, F-6). Functionality has
been verified with the following types: TOREX: XC6204x332xx or XC6401xx42xx.
If the regulator cannot be placed close to the BlueMod+SR, it is recommended to place an
additional low ESR capacitor with at least 10µF as close as possible to the VSUP pins (E-6, F-6 or
C-1).
