The PWM Cape provides 32 channels of PWM output, addressed over an I2C interface. The three pin connectors are wired in a standard servo pinout, and power to the connectors can be provided from a screw terminal block on the end of the board.
The BeagleBone Weather Cape provides weather data for the BeagleBone including temperature, barometric pressure, humidity, and ambient light. These weather input data can be accessed via I2C bus. The BeagleBone Weather Cape also features an LED to indicate that power is applied.
Note: Only revision B is fully compatible with BeagleBone Black. Revision A needs a work around. See below for more details.
The RTC Cape provides time tracking capability for the BeagleBone Black even when the power is lost. This cape features the DS1338 I2C-based real-time clock/calendar and a holder for a coin battery type CR2032. Setup, reading, and setting up time is easy with the provided device tree overlay.
