TL;DR
- Choose Mini for an enclosed, battery-powered receiver when your phone will stay connected for the session.
- Choose Mini S for the same portable form and 25 Hz receiver plus device-side session storage.
- Choose Micro only when its tiny bare-board format and external-power installation solve a real packaging problem.
- Drivurs supports Mini, Mini S, and Micro for live Bluetooth Race Sessions. This page does not claim that saved Mini S or Micro recordings can be imported into the consumer app.
The meaningful difference is not which name sounds newer. It is whether you need an enclosed portable device, device-side storage, or a DIY installation that you will power and protect yourself.
Mini vs Mini S vs Micro: verified differences
| Decision | RaceBox Mini | RaceBox Mini S | RaceBox Micro |
|---|---|---|---|
| Physical format | Enclosed portable unit | Enclosed portable unit | Bare-board module for an installation or project |
| GNSS update rate | 25 Hz | 25 Hz | 25 Hz |
| Power | Integrated 1100 mAh battery; USB-C charging | Integrated 1100 mAh battery; USB-C charging | External 3.5-16 V DC; use a source capable of short 100 mA peaks |
| Device-side storage | No | Yes: RaceBox lists 130 minutes at 25 Hz or 325 minutes at 10 Hz | Yes, but storage does not make it a battery-powered unit |
| Phone connection during capture | Required for the live app workflow | Optional for RaceBox’s own standalone recording; required for a live Drivurs session | Optional for RaceBox’s own standalone recording; required for a live Drivurs session |
| Environmental form | Splash-resistant enclosure | Splash-resistant enclosure | Not waterproof; protect the PCB in a suitable enclosure |
| Best fit | Simple portable live sessions | Portable use plus device-side recording | Permanently or semi-permanently powered DIY packaging |
Mini and Mini S share the same listed 106 g enclosure, 25 Hz multi-constellation receiver, internal battery, USB-C charging, and more than 20 hours of active battery use. Mini S adds internal storage. Micro is a different packaging and power decision: RaceBox describes a 15 g bare board that accepts external DC power and needs thoughtful mounting and environmental protection.
Specifications and bundles can change, so the manufacturer pages below remain the authority. The table is intentionally about durable buying differences rather than temporary price or promotion claims.
Which RaceBox should you buy?
Buy Mini when live phone use is the whole plan
Mini is the clean answer for a driver who mounts the receiver for a session, connects a phone, runs, then removes it. You do not pay for device-side storage you do not intend to use, and you avoid wiring or enclosing a bare board. It is also easier to move between cars than an installed Micro.
Mini is not the right choice if losing the phone connection must not interrupt the device’s own recording. RaceBox’s protocol documentation explicitly limits standalone recording commands to Mini S and Micro.
Buy Mini S when portable standalone capture matters
Mini S is the portable middle ground. It keeps the enclosed battery-powered format while adding internal storage. That matters for long track sessions, motorcycle packaging, or any workflow where the RaceBox device should continue its own recording without a constant phone link.
For Drivurs, keep the boundary clear: use Mini S over Bluetooth during a live Race Session. The existence of device storage is a hardware distinction, not evidence that the public Drivurs app imports those files.
Buy Micro when installation size matters more than convenience
Micro is for integration. Its value is the small board and flexible 3.5-16 V input, not a simpler first-time setup. Plan the regulated power source, strain relief, enclosure, antenna sky view, orientation, and access before buying it. Do not follow Mini charging instructions: Micro has no rechargeable main battery.
Choose Micro for a kart, motorcycle, RC project, or clean in-vehicle install where external power and protection are already part of the design. For an occasional dashboard session, Mini or Mini S is usually the more direct tool.
What Drivurs supports
The current Drivurs supported-device contract lists RaceBox Mini, RaceBox Mini S, and RaceBox Micro. The live flow is:
- Open a Race Session in Drivurs.
- Open the in-app RaceBox connection flow and allow the required Bluetooth permission.
- Scan and select the device in Drivurs; do not pair it first in the phone’s system Bluetooth settings.
- Wait for live telemetry and GPS Ready.
- Run only in a safe, legal environment, then review the completed session.
The original full-size RaceBox, Dragy products, and AiM Solo II are not part of that supported-model statement. If another app is holding the BLE connection, close it before scanning again.
Mounting and repeatability still decide data quality
The Mini/Mini S manual calls for a stable, level position near the vehicle center, with the logo toward the sky, the USB-C port toward the rear, and as few obstructions above the unit as possible. Micro needs the same GNSS sky-view discipline plus electrical and enclosure work.
Do not compare a well-mounted first run with a second run after moving the receiver, changing direction, or changing the road. Satellite geometry, signal blockage, grade, wind, temperature, and tire condition all affect the result. A higher update rate does not remove the need for repeatable conditions.
Before you buy
- Confirm whether you need device-side storage or only a live phone session.
- Decide how the receiver will be held securely with a clear sky view.
- For Micro, document the power supply, connector, enclosure, and service access.
- Check that your phone can grant the current Bluetooth permissions Drivurs requests.
- Choose a closed course, track, or other legal environment before planning acceleration testing.
- Recheck the official specifications and manual at purchase time.
