Aceinna OpenIMU 330


Platform Aceinna IMU: Open-source, embedded development platform for Aceinna IMU hardware. Run custom algorithms and navigation code on Aceinna IMU/INS hardware.

Microcontroller STM32L431CB
Frequency 80MHz
Flash 128KB
Vendor Aceinna


Please use OpenIMU330 ID for board option in “platformio.ini” (Project Configuration File):

platform = aceinna_imu
board = OpenIMU330

You can override default Aceinna OpenIMU 330 settings per build environment using board_*** option, where *** is a JSON object path from board manifest OpenIMU330.json. For example, board_build.mcu, board_build.f_cpu, etc.

platform = aceinna_imu
board = OpenIMU330

; change microcontroller
board_build.mcu = stm32l431cb

; change MCU frequency
board_build.f_cpu = 80000000L


Aceinna OpenIMU 330 supports the next uploading protocols:

  • blackmagic
  • jlink
  • stlink

Default protocol is stlink

You can change upload protocol using upload_protocol option:

platform = aceinna_imu
board = OpenIMU330

upload_protocol = stlink


Debugging - “1-click” solution for debugging with a zero configuration.


You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Aceinna OpenIMU 330 does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.
