This software is experimental and a work in progress. Under no circumstances should these files be used in relation to any critical system(s). Use of these files is at your own risk.

This repo contains, the "Hardware" files to support STM32 based boards on Arduino version 1.6.13 or 1.6.12 (some older versions may also work) including LeafLabs Maple, and Maple mini, and other generic STM32F103 boards

• Ebay search for "arduino maple" (currently costs <$5 with shipping)
• [AliExpress search for "leaflabs maple"] (http://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20150607085526&SearchText=leaflabs+maple)

Some supplier have this board e.g.

* STM32F103VET

*[There is also a STM32F103ZET board which also works, however they are not always available. They have been listed as "STM32F103ZET6 Minimum System Development Board ARM STM32 Cortex-m3 M75"] (http://www.ebay.com.au/itm/1pcs-STM32F103ZET6-Minimum-System-Development-Board-ARM-STM32-Cortex-m3-M75-/291305557264)
