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 OSD click 2 3 1. Introduction 4. Essential features OSD Click with its MAX7456 IC easily displays information such as custom graphics, time and date using 256 user-programmable characters or pictographs. It is NTSC and PAL compatible and displays up to 16 rows x 30 Turn the board upside down so that Turn the board upward again. Make sure characters. MAX7456 has internal sync bottom side is facing you upwards. Place to align the headers so that they are generator. All these features make this board shorter parts of the header pins in both perpendicular to the board, then solder the ideal for security switching systems and soldering pad locations. pins carefully. cameras, industrial applications, consumer electronics and many more. OSD Click is an add-on board in mikroBUS form factor. Its a compact and easy solution for 3. Plugging the board in adding monochrome on-screen display (OSD) click generator to your design. It features MAX7456 Once you have soldered the headers your single-channel monochrome OSD module with board is ready to be placed into desired BOARD integrated EEPROM memory as well as two mikroBUS socket. Make sure to align the www.mikroe.com RCA sockets. OSD Click communicates with cut in the lower-right part of the board target board microcontroller via mikroBUS with the markings on the silkscreen at the OSD click Manual SPI (SDI, SDO, SCK, CS ), RST, LOS, HSYNC and mikroBUS socket. If all of the pins are ver. 1.00 VSYNC lines. The board is designed to use 5V aligned correctly, push the board all the way power supply only.
