Addressable 5050 RGB LED bar (5mm x 5mm) with low current draw. LEDs can be joined by connecting the output of one module to the input of another.
Data line with a very specific protocol, requires a real-time microcontroller AVR, Arduino, PIC, mbed, etc. A minimum 8 MHz processor is required.

2 Cables for 1M Multimeter Meter features:
- Voltage 1000V, 10A CAT III
- Total length 110cm
- Red and black colors

Ideal for connecting TTL RS232 devices to your PC through the USB port. PL2303HX PL2303 USB to UART TTL Cable Module RS232 Converter 4 Pin features:
- Compatible controller PL2303HXA
- 4 pins: 5.0V (red), TxR (green), RxD (white), GND (black)
- 2.5A self-recovery protective fuse
- Supported OS: Win8, Win10, WinME, Win2003, Win XP, Vista, Win 7 The 64-bit Prolific drivers provided by Microsoft through Windows Update will not work with most adapters and will therefore generate the generic "Code 10" error.

Nozzle 1.0 MK8 3D Printer 1.75 Head features:
- Precision Nozzle: 1.0mm
- Material: Copper
- Size: 13 mm x 6 mm
- Suitable for Filament: 1.75mm
- Quantity: 1 unit

The module has two outputs: analog A0 and digital D0
Digital output D0 - signal 0 appears or 1 depending on the threshold setting
The threshold is set with the potentiometer
The sensor can be used for example:
Automatic watering for potted plants
With this module you will be able to measure the humidity of the soil, so that you will be able to control the humidity level of the soil of your plants
Characteristic:
Operation: 3.3V -5V
- Sensitivity adjustable by potentiometer
- Dual output mode: analog and digital
- Red LED - power indicator
- Green LED - indicator digital switching output
- PCB measurements: 3 x 1.5 cm
- Probe measurements: 6 x 3 cm

In the case of a battery pack, the BMS (Battery Management System) balancing protection circuit allows charging and discharging to be individually controlled. That is, the circuit controls that all cells are charged and discharged at approximately the same voltage. The current during charging should be limited, because the cell will "absorb" the current given to it, but a higher current than the one established by the manufacturer (generally a safe current is 1C ) can cause the cell to overheat and, in extreme cases, explode. The same relationship also applies to discharge.
