 8  Productivity Series modules offer several types of industrial grade I/O 
 9   - Analog and Temperature Inputs 
10   - Analog Outputs
11   - Discrete Inputs
12   - Discrete Outputs and Relays
13   - Specialty Modules

19  ## Usage
20  The CircuitPython-P1AM library provides a simple interface for controlling P1000 Modules. See the examples folder for more detailed examples for your products. 
21  
22  ```python
23  relay = base[1][2] # Relay on slot 1 channel 2
24  temperature_sensor = base[3][1] # Temperature sensor on slot 3 channel 1
25  
26  relay.value = True # Set relay to ON
27  temperature = temperature_sensor.value # Read temperature sensor 
28  
29  ```
30  ## What is CircuitPython?
31  
32  CircuitPython is a programming language based on Python that is designed to run on microcontrollers. If you are familiar with Python, you will feel right at home using CircuitPython.

34  ## Compatibility
35  
36  This library is compatible with the P1AM-200. It **is not** compatible with the P1AM-100.

38  # Base Controller #
39  The P1AM Base Controller is the chip that directs communcations between the P1AM-CPU and the P1000 Modules. A P1000 Series power supply or external 24V supply is required to power the Base Controller and modules. On the P1AM-200, all pins used to communicate with the Base Controller are internal to the device, so no header pins are consumed.
