note: The maximum power dissipation (for digital output open drain transistor) is 0.48 W, and the maximum voltage is 30 V or 2.8 A. For example 0.48W / 1V = 0.48A, or 0.48W / 2V = 0.24A etc.
GPIO output has an open drain configuration. Logical state "0" sets the output transistor in a low resistance state and the output is ~0V. Logical state "1" sets the output transistor in a high resistance state and the output voltage depends on the external circuit.
Tamper switch (pin5):
note: Digital input voltage is 0-2.5 V max.
