This article discusses the latest developments of the Sucre4Stem tool, as part of the Sucre initiative, which aims to promote interest in computational thinking and programming skills in K-12 students. The tool follows the Internet of Things approach and consists of two prominent components: 1) SucreCore and 2) SucreCode. SucreCore incorporates an advanced microcontroller packaged in a more compact design and enables wireless connectivity. SucreCode, the block-based visual programming tool, supports two different sets of blocks depending on the education grade, and facilitates wireless communication with SucreCore. At the educational level, Sucre4Stem fosters new group dynamics and encourages students to experiment real-world projects by promoting the "programming to learn" approach to concepts from other disciplines as opposed to the strategy widely applied in schools of "learning to program" in isolation.
