Hobbywing 5V 3A UBEC Step-Down Converter (Hobbywing power converter)
What's in the box?
1 x Hobbywing converter
UBEC's (Universal Battery Eliminator Circuit's) are simply DC to DC step down voltage regulators! This UBEC is perfect for the Raspberry Pi, as it's able to take high voltages (5.5V up to 26V), and outputs a consistent safe voltage of 5V at up to 3A nominal or 5A max! The Hobbywing 5V 3A UBEC is a switch-mode type, which results in it being much more efficient than linear type UBEC's (so your batteries will last longer!)
UBEC's are perfect for applications where you plan to use the Raspberry Pi in a circuit with high voltages such as robots where you'll be driving motors!
Due to the voltage drop caused by the Raspberry Pi, it is recommended to input a minimum of 6.5V from your Batteries to receive a stable 5V output. Anything lower than 6.5V will result in a low voltage warning on the Pi.
Please Note. The Hobbywing UBEC can be set to output either 5V or 6V using an onboard jumper select! Please DOUBLE CHECK your output voltage is correct before connecting your microcontroller or circuit!
Features
- Designed with an advanced switch mode DC-DC regulator IC.
- Battery polarity reversal protection.
- A metal shield covers almost all the electronic components, and a specially made filter is attached to the output wires to significantly reduce the electromagnetic interference.
- The working status is shown by an indicator (LED), which lights when the output is in normal range.
- Output Voltage: 5V@3A or 6V@3A (Changeable with an output-voltage select jumper)
- Continuous output current: 3 Amps
- Maximum output current: 5 Amps
- Input: 5.5V - 26V (2 - 6 cells lithium battery pack or 5 - 18 cells NiMH /NiCd battery)
- Size: 43mm*17mm*7mm (L*W*H)
- Weight: 11g

L293D Dual H-Bridge IC - Solenoid, DC & Stepper Motor Driver (L293D IC H-bridge)
The L293DNE Dual H-Bridge IC is able to run four solenoids, two DC motors or one bi-polar or uni-polar stepper motor, with up to 600mA per channel!
Each chip contains two full H-bridges (four half H-bridges) which means you can drive four solenoids, two DC motors bi-directionally, or one stepper motor. Just make sure they're good for under 600 mA since that's the limit of this chip. They do handle a peak of 1.2A but that's just for a short amount of time. What we like most about this particular driver is that it comes with built in kick-back diodes internally so you dont have to worry about the inductive kick damaging your project or driver
Features
- Dual H-Bridges - run four solenoids, two DC motors, or one uni-polar or bi-polar stepper motor
- Output Current: 600mA per channel (1.2A Max)
- No of Channels: 4
- Input: 5V Logic
- Supply Voltage Range: 4.5V to 36V

Recessed Door Window Contacts Reed Security Alarm Switch (5) (reed switch recessed(5))
No external power supply, connect to wired alarm control panel GND and N.C ports directly!
Description :
These door contact sensors are great for residential and hobby card access systems, as well as a security burglar alarm system. The door position switches operate with an internal magnetic reed switch that closes when the opposing magnet comes within range of the door sensor.
Hence when the door opens beyond the range point the door position switch will toggle from a closed signal to an open signal.
When this happens the access control system or alarm system will sense the change in continuity and will know that the door or window has been opened. When the door or window shuts, the door sensor will notify your security system that the opening has been closed.
Material Shield: Anti-fire ABS
Connecting Mode: N.C.
Rated Current: 100mA
Rated Voltage: (VDC)100
Operating Distance: More than 15mm, Less than 25mm
Rated Power: 3W
