CURRENT MEASUREMENTS
R503 FPM:
When VCC is connected to a 3.31V supply, FPM draws 13.8mA of quiescent current. When
VCC is disconnected (3.3VT connected to 3.31V supply), it draws 2.9uA.
ATmega328P:
MOSFET:
FS5106B high-torque servo:
One of them draws 6.1mA when connected and stabilizes at 4.6mA. The other drew
variable amounts initially (4.7mA, 5mA+, but mostly 4.7). Both draw 4.6mA of
quiescent current with a 5.07V supply.
REMARKS
1. Can't use 3.3V FPM modules with Arduino Uno. The RX and TX lines have
resistors.
2. When the ATmega328P is in normal mode, the MCU + FPM + Servo + linear
regulators draw 30.6mA of quiescent current at 5.07V.
3. When the ATmega328P is in power down mode, the MCU + FPM + Servo + linear
regulators draw 26.0mA of quiescent current at 5.07V.
