2. Soldering the headers Before using your click board , make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 USB UART click 2 3 1. Introduction 4. Essential features USB UART Click with its FT232RL IC gives additional serial UART communication via USB cable. The FT232RL contains integrated 1024 bit EEPROM, 128 bytes Turn the board upside down so that Turn the board upward again. Make sure long receive buffer, 256 bytes long transmit bottom side is facing you upwards. Place to align the headers so that they are buffer, configurable CBUS I/0 pins and entire shorter parts of the header pins in both perpendicular to the board, then solder the USB protocol handled on the chip. The board soldering pad locations. pins carefully. contains RX and TX LED diodes that indicate the transmit and receive data via USB. USB UART Click is an accessory board in 3. Plugging the board in mikroBUS form factor. Its a compact click and easy solution for adding serial UART Once you have soldered the headers your communication via USB cable. It features board is ready to be placed into desired BOARD FT232RL USB-to-UART interface module mikroBUS socket. Make sure to align the www.mikroe.com as well as USB MINI B connector. USB UART cut in the lower-right part of the board Click communicates with target board via with the markings on the silkscreen at USB UART click Manual UART interface. The board is designed to the mikroBUS socket. If all of the pins are ver. 1.01 use 3.3V or 5V I/O level. It has a LED diode aligned correctly, push the board all (GREEN) that indicates the presence of the way into the socket. 0 100000 021231 power supply. 6. SMD Jumper 5. USB UART Click Board Schematic VCCIO VCCIO There is one zero-ohm SMD jumper J1 which E1 is used to select whether 3.3V or 5V I/O level R6 2K2 is used.
