8 Channel 5V Relay Module (Arduino Compatible)

This board provides 8 optically isolated inputs that accept a wide range of voltage, including the 3VDC and 5VDC signals available on the Arduino. This is a great way to switch on or off AC or DC loads using your Arduino!
The relays are single-pole double-throw (SPDT) and are rated for 10A @ 250VAC. The ground for the relay coils is separate from the ground for the input signals.


SMD Parts Vacuum Sucking Pen Handheld Tool

Brand New & High Quality.
Low-cost alternative to tweezers for the pICSMDkup and placement of delICSMDate SMD components.
Soft ESD-sate conductive silICSMDone suction cups won't scratch or damage sensitive parts.
Included 3 size of suction headers , small size for 3g , medium size for 18g and large size for 40g.

Hobbywing UBEC-3A (5V-6V Switchable) 2-6V Lipo

The 3A-UBEC is a switch-mode DC-DC regulator supplied with a 2-6 cells lithium battery pack (or 5-18 cells NiMh /NiCd battery ), and it outputs a consistent safe voltage for your receiver, gyro and servos. It is very suitable for RC helicopter. Compared with the linear mode UBEC, the overall efficiency of the switch-mode UBEC is higher.
