This page provides documentation for the STorM32-BGC board sold by Multi Rotor Mania.

Dos and Don'ts

Please read the tutorial's Dos and Don'ts.

The board is shipped without firmware, it hence needs first to be flashed (see here).

Also, the pins on the connector I2C#2 on the bottom side are reversed as compared to those of connector I2C. Pay attention to that when connecting a second IMU to the I2C#2 port. Fortunately, it is relatively easy to swap the pins on the connectors of the supplied IMU cables.
