USB to UART/I2C/SPI/JTAG Converter, USB to 2-ch UART, or USB to 1-ch UART + 1-ch I2C + 1-ch SPI, or USB to 1-ch UART + 1-ch JTAG,Compatible with Win7/8/8.1/10/11, Linux, Androidetc.

Features 1. Supports USB to 2-ch UART, or USB to 1-ch UART + 1-ch I2C + 1-ch SPI, or USB to 1-ch UART + 1-ch JTAG 2. Supports 2-ch high-speed UART interfaces, up to 9Mbps baud rate, with CTS and RTS hardware automatic flow control 3. Supports 1-ch I2C interface, for easy operating EEPROM through the host computer or programming I2C devices such as OLED and sensor 4. Supports 1-ch SPI interface, with 2x chip select signal pins, capable of controlling 2-ch SPI slave devices at different times 5. Supports 1-ch JTAG interface, can be used with OpenOCD for debugging and testing (Due to the limited testing of chips and software functions, users need to evaluate and test this function on their own) 6. Onboard 3.3V and 5V level conversion circuit for switching the operating level of the communication interface, better compatibility 7.Onboard resettable fuse and ESD protection circuit, provides over-current/over-voltage proof, safe and stable communication Specifications Host interface:USB Power Supply:USB port, 5V Operating level:3.3V/5V (select via onboard switch) 1) USB Connector:USB-B Interface protection:Resettable fuse, ESD protection 2) UART Channel: 2 (the red DIP switch needs to be set to M0 mode) Connector:6PIN IDC connector Baud rate:1200bps～9 Mbps Hardware flow control:CTS and RTS 3) I2C Channel: 1 (the red DIP switch needs to be set to M1/M2 mode) Connector :12PIN IDC connector (the first 4 pins are I2C) 4) SPI Channel: 1 (the red DIP switch needs to be set to M1/M2 mode) Connector:12PIN IDC connector (the last 8 pins are SPI) 5) JTAG Channel: 1 (the red DIP switch needs to be set to M3 mode) Connector:12PIN IDC connector (the last 8 pins are JTAG) Package Content USB TO UART/I2C/SPI/JTAG x1 USB type A to type B cable ~1.2m x1 12PIN cable ~20cm x1 6PIN cable ~20cm (2PCS) x1
