The project of the hardware part is distributed according to GPLv2 license. In the description of the hardware part the following parts are addressed: main controller, input/output module, executing module and programmer module. Three fundamental parts that are included in the platform are discussed in detail: the hardware part, the firmware part and the software tools.
