  • SAE J1939 ECU Simulator Board With USB Port

    SAE J1939 ECU Simulator Board With USB PortThe jCOM.J1939.USB gateway board is a high-performance, low-latency vehicle network adapter for SAE J1939 applications. It allows any host device with a USB COM port to monitor SAE J1939 data traffic and communicate with the SAE J1939 vehicle network. The board supports the full SAE J1939 protocol according to J1939/81 Network Management (Address Claiming) and J1939/21 Transport Protocol (TP). It is also supported by an extensive programming interface for Windows and Linux/Ubuntu applications, including full C/C++/C# source code for short time-to-market developments. => Read more…

  • jBoard-X2 – Industrial CAN Bus / SAE J1939 Prototyping Board

    jBoard-X2 - Industrial CAN Bus / SAE J1939 Prototyping BoardThe jBoard-X2 is an industrial-strength embedded system utilizing the vast capabilities of the NXP LPC1768 (ARM Cortex M3) processor.The LPC176x/5x are Cortex-M3 microcontrollers for embedded applications featuring a high level of integration and low power consumption at frequencies of 100 MHz (120 MHz for LPC1769 and 1759). Features include up to 512 kB of flash memory, up to 64 kB of data memory, Ethernet MAC, USB Device/Host/OTG, 8-channel DMA controller, 4 UARTs, 2 CAN channels, 3 SSP/SPI, 3 I2C, I2S, 8-channel 12-bit ADC, 10-bit DAC, motor control PWM, Quadrature Encoder interface, 4 general purpose timers, 6-output general purpose PWM, ultra-low power Real-Time Clock with separate battery supply, and up to 70 general purpose I/O pins. The LPC176x are pin-compatible to the 100-pin LPC236x ARM7 series. => Read more…


  • jCOM1939Monitor – SAE J1939 Monitor, Analyzer, and ECU Simulator

    SAE J1939 ECU Simulator Board With USB PortThe jCOM1939 Monitor Software is the perfect tool to monitor, analyze, and simulate SAE J1939 data traffic. The system combines our jCOM.J1939.USB that functions as an SAE J1939 to USB (or UART) gateway. A comprehensive and easy-to-use, easy-to-understand Windows software displays not only SAE J1939 data traffic; it also allows to scan the network, simulate an ECU (incl. full node address negotiation features), and respond to data request messages. => Read more…
