Compatible with the Arduino IDE, Stackduino boards automate the process of focus stacking. Version 2.x boards place the emphasis on an enhanced feature-set. The cost of components is correspondingly slightly higher, and the build more challenging due to the use of SMD technology. Version 1.x boards offer a simpler feature-set, but are cheaper and simpler to build. The latest versions of both 1.x and 2.x boards use identical pcb footprints to facilitate development of universally compatible enclosures and accessories.
In addition to several spare IO pins for programming additional features, this version of Stackduino also offers an integrated Micro USB port, and microSD slot for saving settings. An additional header allows straightforward addition of a bluetooth breakout board for interfacing with the controller remotely.
Running at 3.3v, using a switching regulator, this version is optimised for use with batteries in the field. It also features ideal diode power source switching, battery voltage monitoring and automatic shutdown on idle.
This is the first of the v1.x boards to adopt the standard footprint established in v2.x development. It provides the core set of stacking functionality, using (mostly) through-hole components.
