BLK202A-USB-IY Application Field and Working Principle

BLK202A-USB-IY is a kind of display modules in the field of LCD, OLED character and numeric displays. BLK202A-USB-IY is a small sized display with USB connection and an integrated high-speed USB interface for data transmission. It is suitable for applications with a wide range of display resolutions, including but not limited to 256 x 16, 320 x 240 and 384 x 32.

The integrated interface of BLK202A-USB-IY is relatively simple, yet power efficient. It supports both serial communication and 8-bit parallel data input and output. The integrated parallel data output is compatible with 8-bit MCUs such as Arduino, ARM Cortex, and MSP430. Furthermore, the USB interface utilizes USB4 and the embedded USB-I2C controller allows easy communication with host systems. The all-in-one design minimizes external components and reduces the end product size.

BLK202A-USB-IY features a wide operating temperature range, from -30°C to 70°C. This makes it suitable for outdoor applications. In addition, the module has considerable memory capacity, allowing for larger fonts, icons, and other graphical assets to be stored. The module is pre-programmed out-of-the-box. Users only need to select and add the necessary programming commands in the host system.

The operation of BLK202A-USB-IY is quite straightforward. A host system with an integrated USB interface sends the contents to be displayed to the module. The controller inside the module decodes and displays the data in the required format. Depending on the mode (serial communication or 8-bit parallel data input/output), different programming commands are required. For 8-bit parallel data input, user can simply send the content byte by byte; similarly, for 8-bit parallel data output, the content will be transmitted in 8-bits. BLK202A-USB-IY also support serial communication protocols such as SPI, I2C, and UART, allowing for faster communication between host systems and the module.

In conclusion, BLK202A-USB-IY is a powerful and reliable display module for LCD, OLED character and numeric displays. Its integrated interface, wide operating temperature range, large memory capacity, and pre-programmed features make it ideal for a wide range of applications from automotive and industrial displays to consumer products.
