Programmable CAN Bus to USB, Bluetooth, BLE, WiFi Gateway

For the longest time, I had resisted the idea of creating my version of a CAN-to-USB gateway, primarily due to the vast competition. A professional CAN/J1939 development requires a professional CAN-to-PC solution to monitor data traffic. I am pleased with the PEAK PCAN-USB device, as shown in the above image. However, not everybody is willing [...]
