An introduction to ConnDuino

Here, the design of the ConnDuino board is described and shown. The schematic is downloadable. The objectives and intented uses are outlined.

The Arduino in ConnDuino

The article describes the Arduino compatible region of ConnDuino, and its enhancements. Also, the topic of I2C pull-up resistors and their suitable values is discussed.

ConnDuino power supply

ConnDuino offers great flexibility in terms of power supply. Two separate power rails at 5v and 3.3v are implemented on the board, that may selectively supply the micro-controller, the I2C bus lines, or external components. This article describes the options.

ConnDuino intrefaces to add-on modules

Described in this article are the available options for add-on devices that may be plugged to ConnDuino, depending on the specific projects needs.

Expanding ConnDuino: push buttons and breadboard

In the right side of the ConnDuino front, a breadboard has been arranged, for through hole components, allowing for project specific expansion needs. Furthermore, at the top right, a voltage ladder is included to be normally used for push button input, using a single analog pin. This article describes these two features.

ConnDuino quick reference

This is the page, where the functionality of ConnDuino pins and jumpers is shortly described. No in-depth explanations here, only tables lists with quick descriptions.
