STM32L052 Breadboard

Small breadboard compatible development board designed for STM32L052, but all STM32 in LQFP32 package should fit.

Requirements

• Breakout all I/Os
• WS2812 RGB led, blinky things, you know !
• 3.3V LDO regulator
• Easy way to select Vin or Vusb (jumper)
• Easy way to select BOOT0 (jumper)
• USB connector and ESD protection
• 200 to 300 mA mosfet in order to control a more power or other voltages
• Reset button
• Breadboard friendly
• "FTDI" pinout connector for serial communications, and to try ST serial bootloader
• All components on one side, so the board can be easily reflowed with hotplate

Toolchain

Example projets are for Eclipse/OpenSTM32/GCC-ARM, also CubeMX project file is given so it should be easy to generate project files for other IDE.

Code examples

There is few snippets of code in master branch, regarding:

• WS2812b led
• MOSFET control
• RTC

In USB_HID branch, there is custom USB_HID device which allows consumer device (media keys) + keyboard
