JHD1313M1 has two I2C addreses: one belongs to a controller, very similar to the upm::Lcm1602 LCD driver, that controls the HD44780-based display, and the other controls only the backlight. This module was tested with the Seeed Grove LCD RGB Backlight v2.0 display that requires 5V to operate.

        upm_i2clcd.Jhd1313m1 lcd = new upm_i2clcd.Jhd1313m1(1, 0x3E, 0x62);
        
        lcd.setCursor(0,0);
        lcd.write("Hello World");
        lcd.setCursor(1,2);
        lcd.write("Hello World");
        System.out.println("Sleeping for 5 seconds");
        Thread.sleep(5000);
        lcd.clear();
