Uses Eagle 5.1 - Mini48SE - This version is very similar to Maple Mini, but it does not preserve - its pinout. It also heavily utilizes second side to achieve maximal possible density. - As a consequence this version is probably smallest STM32F103Cxx board - it has 0.5" pitch - and size only 50.5x15mm.
