Customer Questions & Answers
What advantages does this GPIO expansion module offer compared with using the Raspberry Pi pins directly?
The expansion module makes the GPIO pins easier to access and organise, reduces the risk of damaging the Raspberry Pi during testing, and allows multiple modules or sensors to be connected via different interfaces. It provides greater safety and tidiness in complex prototypes, although it adds a little height and a possible extra point of failure.
What are the physical dimensions and approximate weight of the module? Could it interfere with standard cases?
Typical dimensions for a GPIO expansion module are approximately 67 mm x 57 mm x 15 mm, with a weight of between 20 and 30 g. In tight setups, it may interfere with very compact cases, especially closed cases over the GPIO pins.
Is soldering or any modification required to install the expansion module?
No. This module uses a 40-pin female header and simply plugs onto the Raspberry Pi GPIO header. No tools, soldering or changes to the main board are required.
What is the recommended current limit when using several peripherals through the module? Can it cause voltage drops?
The limit is set by the Raspberry Pi: in general, it is recommended not to exceed 50 mA per GPIO and 500 mA in total for all connected peripherals. The module introduces minimal resistance (mΩ) but is not designed for high loads. It will generally not cause noticeable voltage drops unless the recommended capacity is exceeded.
Which Raspberry Pi models is this board compatible with?
It is compatible with Raspberry Pi B+, 3B, 2 Model B and 4 Model B.
What does this GPIO expansion board do?
It allows multiplexing of multiple GPIO interfaces to expand the functionality of the Raspberry Pi pins.
Does it include all the components needed for installation?
The package includes the expansion board module, but does not include cables or additional tools.
Is this board suitable for robotics projects?
Yes, it is ideal for projects that require multiple GPIO inputs and outputs, such as robotics and automation.
