It may look like a regular ol' Arduino shield, but don't be fooled, the pyXY (pronounced 'pixie') is a full blown shield-compatible development board. The heart of the pyXY is the Synapse SM700 wireless network module, a mesh network powerhouse that packs a 32-bit ARM7 processor with plenty of on-board memory. What's more, the SM700 can be programmed in SNAPpy, a Python derivative that makes building interactive networks a snap.
