TFT LCD Shield Module SPI Serial Interface For Esplora
The Nextion Enhanced versions are more powerful than the standard ones. Compare to the basic Nextion displays,
the enhanced ones have added some new functions, such as: supporting built-in RTC, supporting save data to Flash,
supporting GPIO, larger flash capacity and larger CPU clock. The enhanced Nextion series has 7 size covers from generic 2.4” to 7.0”.
Nextion Enhanced NX8048K070 is a powerful 7.0” HMI TFT display, with 32MB Flash data storage space, 1024 byte EEPROM,
8192 byte RAM. With GPIO supported, now customers can use Nextion to control external devices.
Nextion is a seamless Human Machine Interface (HMI) solution that provides a control and visualization interface between a human
and a process, machine, application or appliance. Nextion is mainly applied to Internet of thing (IoT) or consumer electronics field.
It is the best solution to replace the traditional LCD and LED Nixie tube.
Nextion includes a hardware part (a series of TFT boards) and a software part (the Nextion editor). The Nextion TFT board uses
only one serial port to communicate. It lets users avoid the hassle of wiring. We noticed that most engineers spend much time in application development but get unsatisfactory results. As a solution to this situation, Nextion editor has mass components such as button, text, progress bar, slider, instrument panel etc. to enrich the interface design. Furthermore, the drag-and-drop function ensures that users spend less time in programming, which will reduce 99% of their development workloads. With the help of this WYSIWYG editor, designing a GUI is a piece of cake.
It’s easy to adapt Nextion family HMI to existing projects- users just need to provide it a UART.
Note: there’s a small power supply test board and a wire for you to test if the electricity supply is enough or not.
Please see below image on how to use it.

Regulator 7905 7912 7915
Voltage regulators are very common in electronic circuits.
They provide a constant output voltage for a varied input voltage.
The 78XX IC is an iconic regulator IC that finds its application in most of the projects. The name 78XX signifies two meaning, “78” means that it is a positive voltage regulator and “XX” means that it provides 5/6/9/12/15/24V as outputSKU: n/a -

Adxl345 Accelerometer
Description
DXL345 Tripple Axis Accelerometer Board is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16g. Digital output data is format as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface.
The ADXL345 Tripple Axis Accelerometer Board is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes less than 1.0°.
Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion and if the acceleration on any axis exceeds a user-set level. Tap sensing detects single and double taps. Free-fall sensing detects if the device is falling. These functions can be mapped to one of two interrupt output pins. An integrated, patent pending 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor intervention.
Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.
