About the OpenSTM32F4 LQFP64 PCB

OpenSTM32F4 LQFP64 is an open source STM32 PCB design by phonght32, published on GitHub under the MIT license. It is a 2-layer board measuring 54 × 68 mm, with 77 components from 33 distinct parts.

Its main chip is the STM32F405RGTx, from the STM32 family. Other key parts include the TPS5430DDA, AMS1117-3.3, MPU-9250, CP2102N and outline. By type, the board carries 26 capacitors, 18 connectors, 16 resistors, 7 diodes, 6 ICs and 2 switches.

It belongs with the sensors and usb & debug tools designs in this gallery.

From the project

openSTM32 board using STM32F4 LQFP64 package. This board designed to perform base control for SLAM and Navigation.There are also many availabe connectors that meet many other application requirements.

Everything about this board: schematic, PCB gerber and BOM are free to distribute under open-source license for users.

The STM32F4 series chip inside openSTM32 board is based on ARM Cortex-M4 with floating point unit (FPU).

This board auto select power supply when both USB and jackDC are powered.
