STM32F4 board with a form-factor of Raspberry Pi (v1.3)

Design by: 9348

A two-layers STM32F4 board, which have a form-factor of Raspberry Pi B+ that allows us to use any case available for this single-board computer:

  • It is based on high-performance ARM®Cortex®-M4 32-bit RISC micro-controller STM32F405RG
  • SMD HSE and LSE crystals
  • Micro SD Card Connector
  • Mini USB Type B Connector with USB EMI filtering and ESD protection. This connector can be used for data transfer and powering
  • A separate +5V DC connector (1 mm X 3.2 mm) instead of Raspberry Pi audio jack
  • 6-pin SWD connector used to program the MCU
  • ESP8266 WiFi Module ESP-11 instead of Raspberry Pi network connector
  • 5-pin connector used to flash and program the ESP-11 module
  • Breadboard-compatible 1x20-pin and 1x10-pin headers connected to free MCU pins
  • Reset button
  • One RGB LED
  • Low power audio DAC with PLL UDA1334ATS
  • 2x class-D mono audio power amplifier IS31AP2005 (2 x 2.95W)
  • 4 pads for audio output instead of Raspberry Pi USB connector
  • SMD size for passive components is 0805
This is an open source project, see for more details
