1. Using CY7C68013A-56 chip: low-power version, enhanced 51 core, 16KB program data area, main frequency 48Mhz, 480Mbps high-speed transmission protocol standard, conforms to USB2.0 specification, and backward compatible with USB1.1. 2. Firmware EEPROM: complete in-system programming scheme, download firmware program directly with USB cable, onboard provides 16K (24LC128) large-capacity program memory (EEPROM), used to store VID/PID and USB firmware, meeting the program space of CY7C68013A demand. 3. All GPIOs are led out through 2.54mm standard headers, which greatly facilitates learners to expand their designs. 4. With the corresponding firmware, the logic analyzer function can be realized through this core board 5. Provide the schematic diagram and related source code in PDF format
