Commercial stacks and development hardware.
What you can buy, what you can license, and what you can build on a bench for the price of a mini-PCIe card. The security library and the PKI integration are the parts that take longest, and they are the parts most evaluation kits leave to you.
What each vendor actually provides.
| Vendor | What they provide |
|---|---|
| Commsignia | Full V2X software stack plus on-board unit, OBU Lite and roadside unit hardware. Claims OmniAir, C2C-CC, C-Roads and CAICT compliance, an integrated security stack, a unified API and ADAS integration. The stack ships on Qualcomm Snapdragon automotive platforms. Model numbers are not confirmed on the current site — verify SKUs before quoting. |
| Cohda Wireless | MK6 / MK6C platform plus V2X-Stack software. The MK6C EVK is the standard C-V2X evaluation kit, also available in a roadside enclosure. Licensed its V2X module to u-blox for the THEO-P1 transceiver. |
| ETAS / ESCRYPT | CycurV2X — an IEEE 1609.2 and TS 103 097 security library plus PKI. Current product naming under the ETAS brand has not been re-verified. |
| AutoCrypt | AutoCrypt V2X stack and AutoCrypt V2X-PKI / SCMS, a cloud SCMS-as-a-service now at version 5.0. Publishes a public Root CA Certification Practice Statement — genuinely useful as a CP/CPS template — and runs a public SCMS interoperability test platform. Where to reach it → |
| INTEGRITY Security Services (Green Hills) | SCMS/CMS certificate management as a service, with production deployments at Tennessee DOT and Macomb County. Also a device management dashboard for OBU and RSU fleets. |
| Keyfactor EJBCA | Acts as an Enrolment Authority only in a C-ITS PKI. Issues enrolment credentials per IEEE 1609.2 and ETSI TS 102 940/941/103 097, OER-encoded explicit certificates. Explicitly does not support ECTL or TLM integration and cannot be a Root CA or AA. The closest thing to an open-core C-ITS CA, and the practical way to stand up your own EA locally. |
| Vector | CANoe.Car2x — simulation, development and test of V2X communication, with a joint end-to-end C-V2X application-layer test solution with Rohde & Schwarz. |
| Elektrobit, Kapsch TrafficCom, Yunex Traffic, Applied Information, Danlaw, TeskaLabs (SeaCat PKI) | Stack, roadside and integrator plays |
What you can put on a bench.
- Cohda MK6C EVK — the standard C-V2X evaluation kit, with a roadside enclosure variant. Quote-based.
- NXP RoadLINK V2X Evaluation Kit 2.0 — co-developed with Cohda, with the SXF1800 secure element for the security side.
- Unex V2X system-on-module and evaluation boards — OmniAir-certified at module level.
- Qualcomm — Snapdragon Automotive 4G/5G reference platforms, plus the former Autotalks CRATON/SECTON line.
- Danlaw AutoLink on-board unit; u-blox THEO-P1 transceiver module.
Real 802.11p frames without a purchase order.
A PC Engines APU2 board with a Compex WLE200NX mini-PCIe card (Atheros, driven by ath9k), running OpenC2X on LEDE/OpenWRT, which bundles the kernel patches for OCB mode — Outside the Context of a BSS — and the ITS-G5 regulatory database changes. Capture with tcpdump, analyse in Wireshark. Total hardware cost is in the low hundreds of dollars against thousands for a software-defined radio.
A Raspberry Pi alone will not do 802.11p. You need an OCB-capable Atheros radio and a patched kernel. A Pi can host the stack; it cannot be the PHY.
Note that this path gives you DSRC / ITS-G5, not C-V2X. There is no comparable low-cost hobbyist path to PC5 sidelink — C-V2X requires a certified modem. The difference →
