2 layer board of 2.51 x 0.81 inches (63.7 x 20.5 mm)
Uploaded: July 05, 2020
Shared: July 13, 2020
Total Price: $10.10

(gerber pack version: v1.0 20200705-0105)

Link to Hackaday project: https://hackaday.io/project/173730-stm32g473cxt6-breadboardable-minimal-system

This is a minimal system of STM32G473CxT6 MCU — all 48 pins, plus +5V power input, are exposed on a compact breadboard-compatible footprint (800 x 2500 mils). Although it looks like a glorified QFP-to-DIP adapter board, it actually has a few features that greatly improve Quality of Life while not adding too much to cost:

  • Micro-USB connector
    • VBUS can be used to power the board
    • Data lines are connected to MCU
  • Flexible power
    • Feed either VBUS or external 5V to on-board 3.3V LDO
    • TVS + reverse-polarity protection on +5V
    • Alternatively use external 3.3V and forget about 5V
  • Cortex Debug Connector (2x5 keyed shrouded 1.27mm pitch)
  • HSE (high-speed external oscillator)
    • Footprint for 4-pad SMD crystal + load capacitors
    • Alternatively free up the pins for GPIO
  • On-board reset button
  • BOOT0 handling
    • 47k pull-down + 1k pull-up (through jumper)
    • Since BOOT0 is multiplexed with PB8 on this package, this setup avoids accidentally back-driving external circuitry.
  • Power LED (+3.3V) and “Blinky” LED (PC13)
  • Silkscreen on both side clearly indicating pinout
  • Headers can be soldered on both sides, although back-side male headers are preferred for breadboard compatibility
