STM32 MAPLE开源电子平台

enly

STM32 MAPLE 是一个开源电子原型平台，  目的是让使用多种学科项目电子使用起来方便。硬件包括一个Arduino板的简单开放硬件设计与爱特梅尔AVR处理器和板载I / O支持。该软件包含一个标准的编程语言和主板上运行的引导加载程序。FEATURES

       

• STM32F103RBT6 microcontroller       
  
• DCDC power supply allows power input voltage from 9 to 30V DC thus making it possible to take virtually any power supply adapter on the market, and to enable applications which are in the industrial power supply of 24VDC.
  

       

• Carefully selected, all of the components work reliably in the INDUSTRIAL temperature range -25+85C so the board can be used in INDUSTIRAL applications.       
  
• ULTRA LOW POWER voltage regulators and the consumption is only few microamps, which enables hand-held and battery powered applications.       
  
• Li-Ion rechargeable battery power supply option with a BUILD-IN on board charger, so that when you attach a battery, it is automatically charged and kept in this state until the other power source (USB or external adapter) is removed and then it will AUTOMATICALLY power the board - no jumpers, no switches!       
  
• UEXT connector which allow many existing modules like RF, ZIGBEE, GSM, GPS to be connected       
  
• Allows RTC - Real Time Clock.       
  
• CAN with driver allows automotive applications       
  
• micoSD-card for data logging       
  
• NOISE IMMUNE design.       
  
• Separate voltage regulator for the Analog part, which allow the ADC to be read correctly without the digital noise pickup.       
  
• The LEDs and the BUTTONs are on the edge of the board so that they can be easily accessed even if the boards have shields on them       
  
• A mini USB connector is used, which is common       
  
• The original Arduino design had a flaw and the connectors were not spaced at 0.1". This makes perfo board use impossible, so to keep the compatibility, we have the same spacing but we added next to this a connector on 0.1" which customers can use with perforated boards       
  
• All signals on the connectors are printed on the top and the bottom of the board, so when you check with a probe you will know exactly which port you are measuring       
  
• 4 mount holes make board attachment easier       
  
• PCB dimensions: (2.7 x 2.1)" ~ (6.9 x 5.3)cm
