Stylus communication channels are described. In implementations, a stylus includes multiple separate and distinct communication channels used to detect the stylus, resolve positions of the stylus and a user relative to a computing device, and exchange data with the computing device (e.g., transmit and receive communications). The stylus may include a first electrode arranged in a tip portion is and a second electrode arranged in a grip area configured to form different corresponding communication channels with the computing device through the tip and through the grip area and a user's hand/body, respectively. A processing system of the computing device, such as a CPU or microcontroller, implements a stylus control module configured to analyze signal patterns derived from signals communicated the first electrode and second electrode and detect the stylus and/or resolve positions of the stylus and a user relative to the computing device based on the analysis.
