Traditional pitboard information. Delivered digitally.
Jimnet Pitboard is a digital alternative to the traditional motorsport pitboard, delivering familiar race information directly to a compact, securely mounted display inside the competing vehicle.
Designed to communicate information typically found on conventional pitboards, including lap times, race positions and pit instructions, the system allows drivers to view essential information without needing to locate and read a physical board at the pit wall.
The display is completely non-interactive for the driver, requiring no buttons, touchscreen interaction or driver-operated controls.
Competition eligibility is subject to applicable event and championship regulations.
Use the Jimnet Pitboard app for iPhone and iPad or the browser-based Pit wall from other connected devices.

Non-interactive driver information
Jimnet Pitboard is designed as a driver information display, not a two-way driver messaging system. The driver cannot compose messages or respond to the pit crew using the display, and no interaction is required while driving. The display does not provide remote control of the vehicle, engine management or vehicle functions.
The pit crew uses the app or web Pit wall to prepare and send information. Display settings are configured before driving. The non-interactive driver interface does not mean that the underlying mobile or MQTT network connection is technically one-way.
How the electronic Pitboard works
The pit crew updates the driver information from the native Apple app or secure web console. The in-car Pitboard Link receives the information through the supported mobile network and makes it available to the optional dedicated display and the vehicle CAN bus.
- Pitboard Link: compact in-car receiver and configurable CAN gateway, approximately 200 g.
- Pitboard Display 4.3: optional colour touchscreen with portrait or landscape layout, light/dark appearance and configurable text colours. Configure it before driving; no driver touchscreen interaction is required.
- Existing motorsport dash: use the CAN output and supplied DBC definitions with a compatible configurable display or logger.
Information available to the driver
- Overall position, class position, both or disabled.
- Four configurable lines for best lap, last lap, gap ahead, gap behind and other supported timing values.
- Custom line labels for the selected dashboard layout.
- Short messages of up to eight characters, including clear instructions such as BOX NOW, PUSH or RAIN.
- Manual or automatic remaining-time countdown.
Supplementary race flag indications
The system can also provide supplementary race flag indications, including red flag and safety car status, where permitted by the applicable event regulations. These indications are supplementary only and do not replace official circuit flags, lights or race-control instructions.
Flag states are configured through the Pit wall; they must not be treated as verified official race-control signals. Supported states include green, yellow, red, safety car, full-course yellow and chequered. Configured alerts can flash on the display or drive compatible dash alerts.
App, team and cloud-service features
These crew-app, team-management and cloud-service capabilities are separate from the non-interactive driver display. Their use depends on the applicable event and championship regulations.
- Protected drafts: prepare changes before sending them to the car.
- Quick messages and flags: reduce typing during a live session.
- Team permissions: invite crew and control who may view or send information.
- Multi-car support: manage more than one racer from a team account.
- Race mode: keep the app awake with light/dark and portrait/landscape layouts.
- Hardware status and settings: check the connected device, firmware, display layout and supported CAN configuration.
- Timing website viewer: open supported provider pages or a custom secure link without copying data from those services.
- Secure saved sign-in: use Face ID, Touch ID or the device passcode on supported Apple devices.
A native Android app is coming shortly. Android, Windows and macOS users can continue to use the browser-based Pit wall.
Designed with Driver and Pit Crew Safety in Mind
- Pit crew safety: sending conventional pitboard information digitally can reduce the need for personnel to hold physical pitboards towards the racing circuit or lean over pit-wall barriers.
- Driver awareness: a consistent, easily readable location inside the cockpit may reduce the need to look towards the pit wall. Secure mounting must preserve the driver’s view of the circuit and access to vehicle controls.
- Clear communication: concise, high-contrast information may improve legibility.
- No driver interaction: information is displayed automatically, without menus or any requirement for driver input while driving.
These are potential benefits of the design, not evidence that the system has been proven safer or reduces accidents.
Competition Mode — Planned / Under Development
Competition Mode is a proposed restricted operating profile. It has not yet been implemented and tested and must not be relied on as an available feature. Proposed features are:
- Configurable limits on message update frequency.
- An option for once-per-lap updates.
- Restriction to conventional pitboard-style information.
- Disablement of vehicle telemetry uplinks.
- Independently configurable supplementary flag indications.
- No driver-operated messaging interface.
- No remote vehicle control.
This is not an approved compliance mode. Once-per-lap updates do not establish eligibility under Motorsport UK rules. The existing crew-app Race mode keeps the app screen awake; it does not apply the proposed Competition Mode restrictions.
CAN, DBC and dashboard compatibility
CAN integration, vehicle telemetry, team management and cloud services are separate from conventional pitboard information. The CAN output described here makes received Pitboard information available to compatible dashboards or loggers; it should not be confused with an unrestricted vehicle telemetry uplink. Ask Jimnet to confirm the availability of vehicle telemetry uplinks and any planned extensions for the selected hardware, firmware and service. Certain advanced features may only be suitable for testing, non-competition use or events where expressly permitted.
The Pitboard Link can publish position, four labelled timing/value channels, remaining time, the eight-character message, connection state, signal state, flag colour and value-validity information over CAN.
The supplied DBC uses the standard Vector CAN database format. Compatible systems may include ECUMaster ADU, AEM CD-series, selected Stack logging systems, Race Technology products and configurable Cosworth Toolset installations. Import support varies by model, firmware and software option; some systems require the published signals to be entered manually. Always confirm compatibility and bench-test the completed configuration before driving.

Competition Use
Jimnet Pitboard is designed to provide the types of information traditionally communicated using a physical pitboard. Eligibility for use in competition depends on the applicable Motorsport UK National Competition Rules, championship regulations and any relevant approvals.
Motorsport UK regulations place restrictions on electronic communication between competing vehicles and teams. Jimnet Pitboard has not yet received confirmation of eligibility for Motorsport UK competition use. Competitors should verify the applicable regulations and obtain any necessary authorisation before using wireless messaging during an event.
Jimnet has requested formal clarification from Motorsport UK concerning Chapter 12, Appendix 4, Article 4.13 of the 2026 National Competition Rules. That clarification is pending; Jimnet Pitboard is not presented as Motorsport UK approved, certified or confirmed compliant.
