The first expansion board for Nextion Enhanced HMI display. Enhanced and higher version Nextion displays supports 8 GPIO, thus we can use this expansion board to control Nextion. The board has 6 buttons, which include Esc, Enter, Left, Right, UP, Down. Also, indicating buzzer and leds are included.
Note: this expansion board can only work with Nextion Enhanced Display, not for basic Nextion Display.
The DRV8825 stepper motor driver carrier is a breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver. The module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver board, so it can be used as a higher-performance drop-in replacement for those boards in many applications.
