What boards using the BMI270 are built for
BMI270: common questions
Where can I find a BMI270 reference design?
Each of the 29 boards on this page is a real design using the BMI270. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the BMI270 use?
Most are built on ESP32 (6), Nordic nRF (5), STM32 (4) and AVR/Arduino (1).
How big is a typical board using the BMI270?
The median is 46 × 36.5 mm, and 24% are two-layer designs.
What is the most popular open source board using the BMI270?
By GitHub stars, TundraIOExpansion by ras-marques, with 29 stars.
Can I simulate one of these boards using the BMI270 before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
