Powering STM32l476-DISCO using CR2032 Battery

STM32l476-DISCO using CR2032 Battery

The stm32l476-disco can be powered by a battery. The board has a socket to place the battery on the backside of the board.

For using the battery you need to do the following steps.

  1. Remove the RST jumper
  2. Remove the jumper marked as CN3
  3. The Jumper JP5 should be set to IDD
  4. The Jumper JP6 should be set to BATT

The battery-powered operation is useful in low power operations.

There is a switch to change the power selection from battery to USB. You need to physically change the jumper location to BATT from 3v3.

The controller gets 3v3 from the st-link section of the board. ST-link gets the power using the USB mini port.

STM32L476vg Discovery Kit Images

  • stm32l476g-disco front
  • stm32l476g-disco back

These are two images of the development board.

Almost entirely the board is made using SMD components. There are some through-hole components.

The back of the development board shows us the different fuses and connections.
At the back, there is a battery holder which can be powered using cr2032.

The top half of the board has an st-link debugger.
