Create your own robot, drone, movable project, or dimmable LEDs with 8 channels of PWM output from the PWM Backpack! Pulse Width Modulation, or PWM, output is commonly used to drive servos, electronic speed controls, and dim LEDs.
PWM has been used from the early days of RC flight to drive analog servos and now is universally used for analog servos, digital servos and speed controllers, both standard speed and those using fast update rates. PWM can also be used to control the brightness of LEDs.
We pinned the 8 PWM outputs to 0.1” (2.54mm) header for easy integration with standard servo connectors. Ground and power are bussed to all of the outputs, simply connect a speed controler (ESC) or regulator (BEC) to provide power to all of your servos or LEDs.
PWM channel 8 is shared with SBUS input, enabling you to optionally configure it to receive data from an SBUS capable receiver. We even provide a configurable solder junction to enable you to provide the receiver with 5V power from the Teensy. With this configuration, you could easily make your own SBUS to PWM converter or even a complete drone autopilot by adding our Motion Backpack to estimate your drone’s orientation and altitude and our GNSS Backpack to get your drone’s location.
The PWM Backpack comes fully assembled and tested.
