Precautions in Use of LCD Modules

1. Avoid applying excessive shocks to the module or making any alterations or modifications to it.
2. Please don’t make extra holes on the printed circuit board, modify its shape, or change the components of the LCD module.
3. Don’t disassemble the LCM.
4. Don’t operate it above the absolute maximum rating.
5. Don’t drop, bend, or twist LCM.
6. Soldering: only to the I/O terminals.
7. Storage: Please store in an anti-static container and a clean environment.
8. Winstar has the right to change the passive components, including R3, R6 & backlight adjust resistors. (Resistors, capacitors, and other passive components will have a different appearance and color caused by the different suppliers.)
9. Winstar has the right to change the PCB Rev. (In order to satisfy the stability, management optimization, and the best product performance, etc, under the premise of not affecting the electrical characteristics and external dimensions, Winstar has the right to modify the version.)
10. To ensure the stability of the display screen, please apply a screen saver after showing 30 mins of fixed display content.
11. Please heat the tape a little before sticking it on the components when removing it; otherwise, the components might be damaged.

• This module has a built-in MCU for serial communication. It provides UART, SPI, and I2C communication protocols. Additionally, the built-in MCU requires a 180ms time upon power-up to initialize the module.

1. UART protocol
   • To enter UART Mode, place jumpers on both JB0 and JB1. The communication format is 8-bit data, no parity, 1 stop bit, and no handshaking. The default baud rate of UART is 9600bps, and it supports five different baud rates: 4800, 9600, 14400, 19200, and 57600 bps. The default baud rate can be restored if Self-Test mode is selected. UART format is follows:
2. SPI protocol
   To enter SPI Mode, keep JB0 open and place a jumper on JB1. The SPI interface allows for receiving data at a clock rate of up to 100KHz. SPI mode has a normally high-level idle clock. When the Chip Select line (CS) is low, data is sampled on the rising edge of the Serial Clock line (SCK). SPI format is as follows:
3. I2C protocol
   To enter I2C Mode, place a jumper on JB0 and keep JB1 open. The I2C interface allows for receiving data at a clock rate of up to 100KHz. The default I2C address is set to 0xA0 (with Read/Write bit)
   • Users have the option to modify this address using the “Change I2C Slave Address” command, but the address value must be an even number (LSB = 0).
     The default I2C address can be restored if Self-Test mode is selected. I2C format is follows:

• In Self-Test mode, the backlight is turned on, and the brightness gradually increases from the darkest tothe brightest level. Then, the display contrast is adjusted, starting from the lightest to the darkest level. Finally, the firmware version, UART baud rate, and I2C address are displayed sequentially
