Want to controller stepper Motor from Arduino, Raspberry Pi or any other Micro-controller? Well then this stepper motor driver will simplify your coding and will give you more flexibility in controlling the stepper motor.

The DRV8825 stepper motor driver carrier is a breakout board for TI’s DRV8825 micro-stepping bipolar stepper motor driver. The DRV8825 features adjustable current limiting, over-current and over-temperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).

This product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver; we therefore recommend careful reading of the DRV8825 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2.2 A output current per coil. 

Buck converter is used when you require to step down the DC voltage from a specified value to a lower value in DC voltage. Unlike AC voltage which you can control easily with a transformer, DC voltages are harder to control because you can’t use a transformer to control it and it requires switching regulators to do so. This 300W 10A DC-DC Step-down Adjustable Constant Current Module can be used to get adjustable output voltage ranges from 1.2V to 30V. The module provides a wide range of current output up to 10A. With the heat sink mounted it can easily manage to run high power applications continuously. The module has onboard multiturn potentiometers for high accuracy voltage and current regulation to provide good stability. As voltage and current are adjustable, it gives very easy to use at multiple Application such as battery charging of multiple voltages like 12V, 9V, 3.6V, 24V, LED Driver power supply, Vehicle Power Supply, etc. i.e. it is a multipurpose module.

This 4G GSM Modem supports 9VDC to 42V DC voltage input on the DC jack input. The extended operating range helps in directly connecting the modem to different power sources like lead acid battery, DC adapters and EV supply. 

There is on board IO level translator for converting the 1.8V UART TX and RX lines of modem to MCU IO voltage level connected to VTRANS pin. 

The A7670x-LASS module has support for Analog audio compared to its predecessor 4G modules like SIM7600 which only had PCM audio interface. You can directly connect a electret MIC to this board as bias circuit is already provided. However for Speaker output you need to use a headphone or amplifier as the signal is weak and needs to be amplified. 

A7670C/A7670E/A7670SA is a very good 4G alternative for 2G modules like SIM900, SIM900A, SIM800 & SIM808. It comes at a very low price and can serve in as a drop in replacement.

CNC 3D Printer Mech Endstop Switch uses a lever switch to detect when it is activated. The switch is wired up so that when activated, it pulls the signal to LOW. There is also an LED on the board that will light up when the switch is activated. It uses a standard 4 pin 100″ pitch header and accepts a standard, old-style CD-ROM audio connector cable.

The mechanical endstop is a simple solution to a simple problem. We want to be able to detect when an X/Y/Z stage has reached its minimum or maximum. Instead of messing with flags or complicated light beam interruption, we use a mechanical switch.

If we place the switch in the path of the stage, then the stage itself will simply close the switch when it moves against it. Other than properly positioning the switch, we do not need to modify the stage at all. If you’re worried about reliability, you can sleep well at night. The switches we use are rated for 1 million operations before failure. Since we only use the switches once per print, that means you’ll be able to do one million prints before having to replace the switch

This TP4056 1A Li-Ion Battery Charging Board Micro USB with Current Protection is a tiny module, perfect for charging single cell 3.7V 1 Ah or higher lithium-ion (Li-Ion) cells such as 16550s that don't have their own protection circuit. Based on the TP4056 charger IC and DW01 battery protection IC this module will offer 1A charge current then cut off when finished.

Furthermore, when the battery voltage drops below 2.4V the protection IC will switch the load off to protect the cell from running at too low of a voltage and also protects against over-voltage and reverse polarity connection (it will usually destroy itself instead of the battery) however please check you have it connected correctly the first time.
