Great Overview Of STM Electronics

The overarching goal of this project is to establish the foundation for designing and coding boards with more advanced stm32f-series microcontrollers. These microcontrollers are arm-based, super common in industry and hobbyist projects, have a large community of support, and a ton of features avr chips don't have like:

• usb support
• real time clocks
• high clock speeds (>100Mhz)
• SDIO communication support
• debugging ports
• Direct Memory Access (DMA)

Development Board

As a development board the primary focus is on testing new hardware (stm32, sensors, power-converts, communication lines, memory, etc). As a result, this board has a ton of pinouts for direct access to almost every pin on the stm32 and all of the communication ports. This board also has a wide voltage input range (3V3 to 14V) in order to allow for a variety of input sources (power supply, battery, usb port, etc). The following is a list of key components on the board.

• Microcontroller
  • STM32F401RCT6
• Sensors
  • IMU--BMI088
  • Magnetometer--LIS3MDLTR
  • Barometer--MS560702BA03-50
• Non-Volatile Memory
  • FM25L04B-G
• Connection
  • Micro-SD
  • Debugging/Programming Port
  • Micro-USB
  • SPI, I2C, UART pinouts
  • Other pinouts
• Power
  • Input
    • 3V3 to 14V
  • Output
    • 5V (buck converter)
    • 3V3 (Low Droput Regulator)

Kicad Parts & Footprints

Currently, most of the parts and footprints are located in a personal library. I will transition the necessary files to the olin rocketry library when the project is closer to completion.
