LadderDIP IV IMPORTANT NOTES

Before starting to use LadderDIP IV please carefully follow the listed notes and guidelines

1) LadderDIP IV is an OEM module. It is sold as OPEN BOARD electronic circuit. The module must be handled carefully. Pay attention to mechanical shocks and any kind of mechanical damage

2) LadderDIP IV is an ESD (Electro Static Sensitive) device. Before handling with your hands be sure to observe all the necessary rules to avoid permanent damages to the module

3) OUTPUT PIN CURRENT: LadderDIP IV pins are directly driven by a NXP microcontroller. Please carefully do not exceed current and limits like specified in this table DC/AC Parameters and absolute max ratings

4) OUTPUT PINS SAFE RESISTORS: Since LadderDIP IV pins can be configured as input or output, some erroneous configurations could generate undesired over-currents when a pin is wrongly used as OUTPUT but the external circuit DRIVES it assuming it is an INPUT. WE STRONGLY SUGGEST TO APPLY ALWAYS A 1K RESISTOR IN SERIES TO ANY INPUT DRIVING CIRCUIT. In this case, even if the pins is erroneously configured as OUTPUT, the limiting resistor will preserve the on-board circuitry.
