USB-Cereal

Soldered USB-Cereal is a powerful and fully open-source development tool that simplifies testing, development, debugging, and manufacturing of devices that support USB Type-C. This device saves time and effort by enabling the capture of debug and factory logs, providing a simple command-line interface, and facilitating firmware updates. The USB-Cereal enables simple UART serial communication with the host device through the sideband pins. This device can perform general closed-case debugging, testing, and data capture on devices with USB Type-C and doesn’t require a USB stack to be brought up. The USB-Cereal can also perform low-level debugging with USB drivers not yet fully loaded and closed-case firmware update procedures. This device can capture development logs with the Device Under Test (DUT) closed up, without any jumper wires hanging around, and without any extra connectors. The USB-Cereal supports up to 3Mbps rate for both 1.8 V and 3.3 V signal levels. This device features onboard green and orange LEDs to indicate both TX and RX operations. The USB-Cereal mechanically supports USB-C plug.
