I don’t believe there is an accelerometer built-in.
Attaching an external one is certainly possible though. Using an I2C sensor would be best (use the audio mezzanine if you need level shifting to connect it).
Alternatively you could take a look at the Neonkey mezzanine. This has a built in accelerometer (together with many other sensors) although I don’t think there are any tutorial guides on how to connect it to the DB410C.
