A compact modular embedded device. A base module includes a processor, a memory medium operable to store a bootloader for executing graphical programs, a buss and a power input coupled to the processor, memory medium, and bus, for receiving power from a power source and providing the received power to the processor, memory medium, and bus. The base module can couple to a host computer via a transmission medium, receive a program from the host computer, and store the program in the memory medium. The base module may couple to extension modules via the bus in a stacked fashion, where the base module and the extension modules each include a respective substantially planar circuit board that when stacked are substantially parallel. Each extension module provides respective functionality for the device. The base module can execute the program to perform a function in conjunction with the extension modules.
