{"product_id":"usb-to-uart-i2c-spi-jtag-converter","title":"USB To UART\/I2C\/SPI\/JTAG Converter","description":"\u003cp\u003eThis USB-to UART\/I2C\/SPI\/JTAG converter gives flexible configurations including dual-channel UART, or a combination of UART, I2C, and SPI, as well as a configuration that supports UART with JTAG functions. It has high-speed data transmission with two UART interfaces supporting up to 9Mbps baud rate, complete with CTS and RTS for reliable hardware automatic flow control.\u003c\/p\u003e \u003cp\u003eIf your project involves memory devices and sensors, the converter provides a single-channel I2C interface, which is perfect for operating EEPROMs or programming I2C devices like OLED displays and various sensors. The SPI interface has two chip-select signal pins that allow control over two SPI slave devices independently.\u003c\/p\u003e \u003cp\u003eAdditionally, the JTAG interface is used for debugging and testing with OpenOCD, although you should perform their evaluations and tests due to the limited testing of chips and software functions. To provide wide compatibility with various systems, the converter includes an onboard 3.3V and 5V level conversion circuit, making it easy to switch the operating level of the communication interfaces.\u003c\/p\u003e \u003ch2\u003eFeatures\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eUSB to 2-channel UART, or USB to 1-ch UART + 1-ch I2C + 1-ch SPI, or USB to 1-ch UART + 1-ch
