Connections and Pin Definitions
The BASIC Stamp 2 is used as the example processor in this documentation. The MLX90614 module
mounts into a socket terminal or breadboard. Connection to the BASIC Stamp module is made via five
connections using 3 I/O pins. Before installing the MLX90614 module, you should perform the following
steps:

1. Clear the current BASIC Stamp program to ensure that all pins are set to inputs. The simplest
2. Disconnect power from the BASIC Stamp circuit.
3. Connect five separate wires between the MLX90614 module and the BASIC Stamp module.
4. Reconnect power to the BASIC Stamp circuit and program as desired.
program to do this contains just one statement:
Additional modules maybe connected to the serial bus provided each has a different slave
address.
