US Patent 10954911 Control and communication module for light-duty combustion engine

—In at least some implementations, a control and communication system for a light-duty combustion engine includes a circuit card, an ignition circuit carried by the circuit card and configured to control an ignition timing of the engine, and a short range wireless communication circuit carried by the circuit card. The communication circuit may include a Bluetooth Low Energy antenna. The ignition circuit may include an ignition capacitor that when drained induces an ignition pulse adapted to fire a spark plug. The system may further include a microprocessor that is coupled to and controls the ignition and communication circuits, and/or a clocking circuit adapted to provide a clocking frequency associated with the timing of the ignition circuit and associated with the communication circuit via a short range wireless communication protocol. The clocking circuit may include a crystal oscillator.
