Shopping for a data acquisition recorder isn't one-size-fits-all. You might be chasing lap times and GPS speed traces, or you might be building a benchtop setup that measures electrical signals across multiple inputs. These two very different tools-the Racebox Micro GPS Speed Meter & Telemetry Data Logger and the Keithley DAQ6510 Data Acquisition DMM6500 Multimeter System-sit at opposite ends of the price scale and serve opposite workflows.
Quick Verdict
If you're after lap timing, GPS speed, and telemetry logging on a budget, the Racebox Micro is the clear choice. If you need a benchtop data acquisition system with multimeter function and two slots, the Keithley DAQ6510 is worth the larger investment.

Where the Racebox Micro Wins
The Racebox Micro's biggest advantage is how well it fits the vehicle telemetry use case. It supports Bluetooth with both the proprietary RaceBox Protocol and the NMEA standard, so you can connect it to a phone, tablet, or custom app. Standalone storage means you don't need a phone running for the whole session, and the API documentation opens the door for DIY projects. It's compact, so it can sit in a car without becoming a permanent fixture, and it's designed for the kind of quick, precise GPS logging that lap and drag timing require.
Where the Keithley DAQ6510 Wins
The Keithley DAQ6510 is designed as a data acquisition and DMM6500 multimeter system. It's clearly aimed at bench work rather than vehicle telemetry. If your projects live on a workbench and you need both data-logging and multimeter capability, this is the system for you. For someone already using a DMM-style workflow, the DAQ6510 brings data acquisition into the same unit, so you're not juggling separate tools when you want to log readings over time.
Product Notes
Racebox Micro GPS Speed Meter & Telemetry Data Logger [BOX001
The Racebox Micro is built around a 25Hz GNSS receiver that delivers ten-centimeter positioning precision, which is why it's such a strong fit for lap timing and drag runs. It also speaks both the proprietary RaceBox Protocol and NMEA over Bluetooth, so you can pair it with phones, tablets, or custom software. Standalone storage is another practical plus; you can log a session without keeping an app connected the entire time. The API documentation makes it accessible to DIY developers. The limitation is that this is a GPS and telemetry logger, not a general-purpose electrical measurement instrument. If you need voltage, current, or resistance readings, you're looking at the wrong product.
Keithley DAQ6510 Data Acquisition DMM6500 Multimeter System
The Keithley DAQ6510 is a data acquisition system that also carries DMM6500 multimeter capability, and the two-slot configuration is a concrete feature that sets it apart from a single-purpose GPS logger. That makes it a sensible pick for a bench setup where you want both data-logging and multimeter functions in one unit. The main reason to choose it is that it addresses the measurement side of data acquisition recorders rather than the GPS side. The limitation is the used condition: this is not a new instrument, and for precision lab work that's an important consideration.
Final Choice by Use Case
Choose the Racebox Micro GPS Speed Meter & Telemetry Data Logger if your project involves vehicles, lap timing, speed traces, or GPS-based telemetry and you want a compact, standalone logger. Choose the Keithley DAQ6510 Data Acquisition DMM6500 Multimeter System if you need a benchtop data acquisition and multimeter system with two slots and you're prepared for the higher cost and used condition.
