Board Design Weekend - 000

Introduction

  • Design a simple board
  • Design a board with no SMT parts
  • STM32F4x1 "Black Pill"
  • Lego Mounts
  • PMOD-eque pinouts
  • Maybe a fancy 12 pin connector idea I have
  • Maybe some QWIIC connectors
  • Maybe a fancy debugger connector

Post scratch Layout notes

  • STM32F4 Black Pill
  • Ethernet Connector (as debugger)
  • 5xPMOD headers
    • 1x SPI
    • 1x I2C
    • 1x UART
    • 2x GPIO
    • NOTE: ALL PMODs repeated 3x
  • 1x12 pin "Everything" connector
  • 2x 1x6 Mounting Holes
  • QWIIC connectors (common to I2C PMOD)
    • Probably on the bottom
    • 1: GND
    • 2: VCC
    • 3: SDA
    • 4: SCL
