PEAK-System’s CAN FD lineup covers four distinct jobs: connecting a PC to a CAN FD bus, adding configurable I/O, bridging RS-232 equipment to CAN, and integrating sensor data into a CAN FD measurement chain. For CANopen FD in particular, start with the PCAN-MicroMod FD family—but verify the exact model, firmware mode, and licensing rather than assuming every configuration ships ready for CANopen FD.
What PEAK-System’s CAN FD portfolio does
CAN FD allows up to 64 data bytes in a frame, compared with the smaller payload of classic CAN, and supports a faster data phase. PEAK-System’s products put that capability to different uses: PCAN-USB FD connects a computer to a bus for monitoring and development; PCAN-MicroMod FD products add configurable inputs and outputs; PCAN-RS-232 FD bridges serial equipment; and PCAN-GPS Pro FD sends navigation and motion-sensor data over CAN or CAN FD.
These devices are not interchangeable. A USB interface is for PC-based access; it is not itself a distributed I/O module or a serial converter. Conversely, the configurable modules are intended for embedded or machine-side use, not as a substitute for a PC interface when you need to inspect a bus from a computer.
Which PEAK product fits the job?

CANopen firmware licensing is available through Embedded Systems Academy, according to PEAK-System. | Exact model, I/O type and count, firmware mode, license, and whether CANopen FD is supported in that model’s operating-mode table. |
| PCAN-RS-232 FD | Connecting RS-232 machines, PLCs, sensors, or actuators to a CAN or CAN FD network | Converts traffic between RS-232 and CAN/CAN FD. | Freely programmable in C/C++; PEAK-System supplies a GCC ARM development package and examples. | Whether the application needs custom conversion logic and whether the serial device’s interface and data format match the integration. |
| PCAN-GPS Pro FD | Navigation and motion measurement for CAN/CAN FD systems | Transmits over CAN 2.0 A/B or CAN FD; PEAK-System specifies CAN FD operation up to 10 Mbit/s and navigation-data update rates up to 25 Hz. | Configurable sensor module with a dual-core M7/M4 microcontroller, magnetometer, gyroscope, accelerometer, and u-blox NEO-M9N receiver. | Required sensor outputs, CAN rate, mounting and sealing requirements. The aluminum housing is rated IP50 or IP54 depending on sealing plugs. |
Some comparison details—such as PCAN-USB FD channel count and the specific I/O counts for the MicroMod FD variants—are not stated in the cited material here. Check the specification for the exact item number before selecting hardware; a family name alone does not settle those requirements.

PCAN-USB FD: the PC connection for CAN FD work
PCAN-USB FD is a USB 2.0 interface for connecting a computer to a CAN or CAN FD network. PEAK-System specifies CAN 2.0 A/B and CAN FD support, selectable ISO and Non-ISO CAN FD modes, a maximum 64-byte CAN FD data field, and data-phase bit rates from 25 kbit/s to 12 Mbit/s. The stated rate is for the CAN FD data phase, not a claim that every bus or node can communicate at 12 Mbit/s.
For diagnosis and development, PEAK lists one-microsecond timestamp resolution, error-frame and overload measurement, and induced error generation. The product information also lists galvanic isolation up to 500 V, PCAN-View monitoring software, and PCAN-Basic development interfaces. Match the interface’s mode and timing to the network: a mismatch between ISO and Non-ISO CAN FD operation can prevent otherwise compatible nodes from communicating.

PCAN-MicroMod FD: configurable I/O and the CANopen FD route
The PCAN-MicroMod FD family combines an Arm-based microcontroller, a CAN FD interface, and configurable inputs and outputs on a plug-in board. PEAK-System lists Evaluation, Analog, Digital, ECU, and DR CANopen Digital 1 variants. Multiple modules can be configured independently on one bus, making the family relevant to distributed control and measurement rather than only PC-based diagnostics.
CANopen FD support is a combination of hardware model and firmware, not a blanket assumption about every unit’s delivered configuration. PEAK’s Digital product information says the PCAN-MicroMod FD products can alternatively run CANopen firmware, with licenses available from Embedded Systems Academy. The evaluation manual’s operating-mode table distinguishes support by model across CAN, CAN FD, CANopen, and CANopen FD. Check that table for the exact variant and confirm the license and firmware mode before basing a system design on CANopen FD.

What the CANopen profiles mean
For CANopen operation, the manual identifies CiA 301 and CiA 1301 communication profiles and CiA 401/401-B/F device profiles. In practical terms, the communication profile and device profile describe how a node communicates and presents its I/O functionality within a CANopen network. Confirm the specific profile and firmware behavior needed by the controller and other nodes; the family label alone does not establish every application-level object or feature.
Firmware update implications
PEAK-System’s CANopen firmware history lists version 1.12.6 dated 2025-10-23, with fixes for frequency and duty-cycle boundaries and 16-bit analog-output representation. The preceding entry, version 1.12.5 dated 2025-01-30, records minor improvements. These are dated history entries, not a guarantee that 1.12.6 is the latest firmware available in October 2026; check PEAK’s current download and firmware history before updating.

PCAN-RS-232 FD for serial equipment
PCAN-RS-232 FD converts traffic between RS-232 and CAN/CAN FD, addressing equipment that has a serial interface but needs to exchange data with a CAN-based machine or controller. It is freely programmable in C/C++ and includes a GCC ARM development package and examples. That programmability makes it a candidate when the translation rules are application-specific; it does not mean a particular protocol mapping is automatic or supplied for every serial device.

PCAN-GPS Pro FD for sensor chains
PCAN-GPS Pro FD combines a u-blox NEO-M9N receiver with a magnetometer, gyroscope, and accelerometer, controlled by a dual-core M7/M4 microcontroller. PEAK specifies navigation-data updates up to 25 Hz and CAN FD transmission up to 10 Mbit/s, as well as CAN 2.0 A/B support. Its aluminum enclosure is rated IP50 or IP54 depending on the sealing plugs used. Check the required enclosure protection and sensor outputs against the actual installation rather than treating the higher IP rating as universal.
What the roadmap does—and does not—establish
PEAK-System’s November 2025 catalog listed CAN (FD), CANopen (FD), custom firmware, and planned J1939 (FD) operating modes across the PCAN-MicroMod FD family. It described J1939 (FD) support as planned for Q1 2026. That date has passed, so the catalog is evidence of a historical plan, not confirmation that J1939 (FD) is now available. Verify current availability with PEAK-System for the specific model and firmware.
Quick Recap
How to choose a PEAK CAN FD product
- For PC monitoring, diagnostics, or application development: start with PCAN-USB FD, then verify channel count, connector, isolation, data-phase rate, ISO/Non-ISO mode, and the PC software/API requirements.
- For distributed CANopen FD I/O: evaluate the relevant PCAN-MicroMod FD Digital variant or DR CANopen Digital 1. Confirm model-level CANopen FD support in the manual, the installed firmware mode, and the licensing arrangement.
- For RS-232 equipment: consider PCAN-RS-232 FD when a serial-to-CAN/CAN FD bridge with programmable conversion logic is needed.
- For positioning and motion measurements: consider PCAN-GPS Pro FD when its specified sensor set, update rate, CAN FD rate, and enclosure rating meet the installation requirements.
Before integrating any of these devices
- Confirm each node supports the intended bus mode: classic CAN, CAN FD ISO, Non-ISO CAN FD, CANopen, or CANopen FD.
- Check arbitration and data-phase bit rates against every node on the bus; a device’s maximum supported rate is not a network-wide operating guarantee.
- For PCAN-MicroMod FD, confirm the exact model’s operating modes, firmware version, CANopen license, and I/O configuration.
- For firmware changes, consult the current model-specific instructions and account for PEAK’s note that CANopen and regular PCAN-MicroMod FD firmware updates include one another.
- For rugged or vehicle installations, verify the actual environmental, electrical, and connector requirements in the exact product documentation; the summarized details above do not establish suitability for every automotive installation.
