ITEM NAME:1.8 inch TFT Display Module Breakout SD SPI ST7735R DIY for Arduino Nano W1B2 1.8 inch TFT Display Module Breakout SD SPI ST7735R DIY for Arduino Nano W1B2 Controller Chip: onboard high performance microcontroller chip Control Chip: onboard CH340 USB control chip LED Indicator Lamp: onboard power LED indicator lamp and relay status LED indicator lamp Relay: onboard 5V, 10A/250V AC, 10A/30V DC relay Protection Function: overcurrent protection and relay diode follow current protection function colour: blue Material: metal Communication Protocol: LC USB switch defaults communication baud rate: 9600bps LC USB switch communication protocol: Data (1): start mark (defaults 0xA0) Data (2): switch address code (defaults 0x01, means the first channel switch) Data (3): operation data (0x00 is OFF, 0x01 is on) Data (4): check code For Example: Open the USB Switch: A0 01 01 A2 Close the USB Switch: A0 01 00 A1 Using Methods: Step 1: plug the USB relay module on the computer, and install CH340 USB to serial port chip driver Step 2: open the STC-ISP, SSCOM32 serial port debugging software, and select the baud rate as 9600. Send A0 01 01 A2 to open the relay in the form of hex, select manual send or auto send Manual Send: select the baud rate as 9600, check "HEX send"; input the instruction A0 01 01 A2 or A0 01 00 A1, then click "send"; then you can open or close the relay Auto Send: select the baud rate as 9600, click "expand" SSCOM32 interface; input instruction A0 01 01 A2 and A0 01 00 A1, check "HEX send" and input the interval time of auto cycle sending, check "auto cycle send", then the relay can automatically cycle to open or close Package Includes: 1 * Module Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm..Step 1: plug the USB relay module on the computer, and install CH340 USB to serial port chip driver. 1 Module. Step 2: open the STC-ISP, SSCOM32 serial port debugging software, and select the baud rate as 9600.
