This is the region where add-on devices may be plugged to ConnDuino. Several pin headers exist here, which interface the pinout of some common modules, such as:
- TFT display screen
- LCD 16x2 display
- Radio receiver or transmitter modules
- Real time clock (RTC) module
The mapping of these pin headers to the Arduino compatible digital or analog pins (in other words the Atmega328p pins), has been designed in such a way that no conflict occurs. This means that all pin headers may be utilized concurrently, to install the respective number of add-on devices, while still some digital and analog pins remain free for other uses!
In this article the details for each installable add-on module are described.
