A power tool with a combined printed circuit board (PCB) that reduces internal wiring of the power tool and provides a large amount of air flow to internal components. In some instances, the combined PCB has a surfboard shape and includes a motor control unit and power switching elements (Field Effect Transistors or FETs). The combined surfboard PCB is located above the trigger, but below the motor and drive mechanism. In other instances, the combined PCB has a doughnut shape and is located coaxially with a motor shaft. The combined PCB may be positioned between a doughnut-shaped control PCB and the motor.

A data logger device for a power tool including a housing, a power tool interface provided at the top of the housing and configured to be received in a corresponding interface of the power tool, and a battery pack interface provided at the bottom of the housing and configured to receive a corresponding interface of a battery pack providing operating power to the power tool. The data logger also includes a tool terminal block, a battery terminal block provided, and bus bars connecting the tool terminal block to the battery terminal block to provide pass through power from the battery pack to the power tool. The data logger is configured to obtain data related to power tool operation, and export, using a transceiver, the data to a user device.

A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a saw arm, a brushless motor supported by the saw arm, and power electronics positioned outside the motor for supplying power to the motor. The power electronics are coupled to a structural component of the miter saw to utilize the entire mass of the structural component as a heat sink to dissipate heat generated by the power electronics.
