====== dipCoreF4 ======
{{ :antichambre:fichier_29-08-2018_18_32_51.png?400 |}}
**A reduced Core for your MIDIbox App, an STM32F405RG in a DIP40 format.**
\\
\\


===== Features =====
  * MIOS32 uses same processor family and drivers(no deep change).
  * Same internal hardware as Disco or wCore (speed, memory, peripherals, etc...) .
  * Board pinout and package compatible with a MIOS8 PIC 8-)
  * USB connector onboard.
  * 5V power input and led.
  * 3.3V regulator and led on board.
  * 74HCT541 on board for the 5V output ports.
  * User and Reset buttons.
  * 2 user leds.
  * 8 extra pins for USB, buttons and leds.
  * Your favorite Core is now a current component easy to integrate.

All commons MIOS32 ports are available except:
  * General purpose J10x ports were removed.
  * LCD port was reduced to a serial one, no more pins J15.D0-D7 , no back-light power supply.
  * 2 UART only(2 MIDI In/2Out).
  * 2 AIN channels only(e.g. pedal inputs)

<WRAP column 35%>
The 405RG is a TQFP64, a 10x10mm package and only 64 pins.\\

=== In MIOS32 ===
We use the same peripheral drivers same family, some compilation defined conditions were added for the specific pinout and type, number of ports.
