ACME by BayLibre is an extension (cape) for the BeagleBone Black, designed to provide multi-channel power and temperature measurements capabilities.
It comes with power (equipped with a power switch) and temperature probes, turning it into an advanced all-in-one power/temperature measurement solution.

Protocol
ACME probes are connected to I2C bus #1 of the BeagleBone Black via the ACME Cape.
The components used to do actual measurements (INA226 & TMP435) are supported in mainline Linux. The drivers expose a standard interface via Linux sysfs pseudo file system.
ACME driver for libsigrok uses said interface to acquire measurement samples and control the Cape (change shunt resistance configuration, cut-off power to measured devices etc.).
