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
