Seriously Pro Racing F3 Mini

The SP Racing F3 Mini design is:

• Innovative - New, smart and practical design features.<?xml:namespace prefix = "o" />
• Flexible - Corners are removable for micro frames, buttons and transponder can be detached and relocated.
• Durable - Though-hole connectors for all main I/O for crash-proof installation.
• Stackable - Mount to your PDB or OSD.
• Compact - Center of PCB measures 36x24mm, main area 36x36mm, transponder section is 36x6mm, entire board just 36x43mm.
• Professional - Symmetrical, Neat and Tidy.

The hardware was designed by the lead developer of Cleanflight to be more capable than the previous-generation STM32F1-based boards and to set the benchmark for a fully-featured STM32F3-based mini board.
