Use a magnifying glass to inspect the pins – you’ll see tiny dark rings around some pins. With a fine-tip soldering iron (350°C) and flux, reflow each pin of the microcontroller and the CAN transceiver (usually an MCP2551 or TJA1050). Add a small amount of fresh solder. : ~1,450 In this long-form guide, we will
