USB-to-serial debug boards are commonly used for board bring-up, checking for issues when a board does not boot, or accessing the serial console in systems without networking or video output. You’d just connect GND, Tx, and Rx wires to the target board, and a USB cable to the host, before running a terminal program like Putty, Minicom, or Bootterm with the correct parameters, and you should be good to go. That’s the theory, but sometimes Tx and Rx may be inverted, the baudrate is not advertised, and so on. So Excamera Labs decided to make the TermDriver 2, an improved USB-to-serial with a small built-in display to more easily debug those issues. It can also be used in standalone mode, showing the serial console output on the tiny screen without having to connect it to a host. TermDriver 2 specifications: MCU – Raspberry Pi RP2040 dual-core Arm Cortex-M0+ MCU @ […]

HydraLink USB-to-Automotive Ethernet dongle works over a single twisted pair (Crowdfunding)
HydraLink is a compact USB-to-Automotive Ethernet dongle that supports 100BASE-T1 and 1000BASE-T1 standards over a single twisted pair (no large RJ45 connector needed) and provides a solution for diagnosing, testing, and prototyping automotive networks. The rationale behind HydraLink is that the automotive sector is undergoing a shift from CAN-based systems to advanced Automotive Ethernet networks like BroadR-Reach (802.3bw) that allow multiple in-vehicle systems to simultaneously access information over unshielded single twisted pair cables. So as I understand it, the HydraLink is the modern equivalent of OBD-II USB scanners relying on Ethernet instead. HydraLink specifications: Networking – 100 Mbps or 1000 Mbps automotive Ethernet via 2.54 mm pin header (Note: the board below features a Broadcom BCM89811 BroadR-Reach automotive Ethernet RGMII transceiver limited to 100BASE-T1 data rate) USB – USB 3.0 Gen 1 Type-C port Misc – Link activity and link speed LED indicators Power Supply – 5V via USB interface […]
