CCC23 - MuHack Badge and MuTag
CCC23 - MuHack Badge and keychain So you stumbled upon this strange circuit board and you want to know more about it? Well, you are in the right place! The MuHack Badge This circular board is the official MuHack Badge . It’s a board with an RP2040 (a 32-bit dual ARM Cortex-M0+) as main microcontroller running MicroPython , and the Bosh Sensor Hub BHI160(B) as secondary microcontroller. This latter integrates a 3-axis gyroscope, a 3-axis accelerometer and a programmable microcontroller. The sensor also contains pre-installed fusion software and specific algorithms that enable always-on motion sensing. The BHI160(B) is also connected to the Bosh BMM150 magnetometer, a low power and low noise 3-axis digital geomagnetic sensor. Thanks to the BHI160(B) and the BMM150, the MuHack Badge can be used to measure the orientation of the board in space, crushing a full 9DOF IMU quaternion , as well as activity recognition , such as step counting, wakeup/pickup/tilt/glance gesture and other motion related features. Note how the colors remain in the same position as the board is rotated
