The AiM PDM08 is the compact power distribution module for builds where 8 programmable high-side outputs cover all requirements. It packs the same solid-state protection, data logging, ECU connection, and AiM expansion CAN found on the larger PDM32 into a 161 × 101 × 51 mm, 370 g aluminium housing — small enough for sill-mount in a single-seater or behind the dash in a hillclimb car.
Eight independently controlled high-side outputs handle the full range of motorsport circuits: ignition, fuel pump, water pump, cooling fan, dash, and auxiliary loads. The highest-rated output (25 A) handles the fuel pump or starter circuit with a series flyback diode for solenoid protection. All outputs are configurable for current limit, PWM soft-start, inrush limit, fault retry count, and retry interval. Per-output multicolour LEDs show enabled, activated, and fault states at a glance.
The built-in 4 GB logger records all PDM inputs and outputs alongside ECU data via CAN or RS232. Paired with an AiM GPS09c module, the PDM08 adds automatic lap timing and track position. It drives a 5″, 6″, or 10″ AiM dash display as primary controller, removing the need for a separate data logger. Two camera inputs allow a reverse or driver-facing camera to be displayed on the dash.

FAQ
How do I choose between the PDM08 and PDM32?
Count the switched circuits your build requires. A club racing single-seater typically needs 6–8 circuits: ignition, fuel pump, water pump, fan, ECU, logger, and dash. The PDM08 covers that entirely. A full GT or endurance car with lighting, DRS, wiper, reverse camera, active aero, and multiple fans will need 15–32 circuits and the half-bridge outputs of the PDM32. If you are near the 8-circuit limit, choose the PDM32 for headroom.
Can I add the GPS module and a dash later if I buy the base PDM08?
Yes. The GPS09c module connects to the PDM08’s CAN expansion port and can be added at any time. An AiM 5″, 6″, or 10″ dash can be added to the same CAN network. The PDM08 acts as the system controller for both. Contact us to confirm which dash model is appropriate for your build.
Does the PDM08 replace my data logger?
Yes. The PDM08 includes a 4 GB internal data logger that records all PDM inputs, output states, and ECU data. For most club and semi-professional builds, this eliminates the need for a separate AiM EVO5 or standalone logger. If you need more than 8 analogue inputs or dedicated wheel speed channels beyond what your ECU provides, add an AiM EVO5 as a CAN expansion device.
Are all outputs PWM configurable?
Yes. All 8 outputs support PWM and soft-start/stop. This allows speed control for cooling fans (ramp up from idle to full speed), gradual ignition arming sequences, and inrush current management for high-capacitance circuits. Duty cycle, frequency, soft-start ramp time, and current trip thresholds are set per output in Race Studio 3.
