Hemal Electronics

This is a 5V, 10A 2-Channel Relay interface board. It can be used to control various appliances, and other equipments with large current. It can be controlled directly with 3.3V or 5V logic signals from a microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).

It has a 1x4 (2.54mm pitch) pin header for connecting power (5V and 0V), and for controlling the 2 relays.

The pins are marked on the PCB:-

• GND - Connect 0V to this pin.
• IN1 - Controls relay 1, active Low Relay will turn on when this input goes below about 2.0V
• IN2 - Controls relay 2, active Low Relay will turn on when this input goes below about 2.0V
• VCC - Connect 5V to this pin. Is used to power the opto couplers

Specification:-

• High current relay, AC250V 10A, DC5V 10A
• 2 LEDs to indicate when relays are on
• Works with logic level signals from 3.3V or 5V devices
• Opto isolation circuitry

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 finishe

1. Connect micro USB cable for power, or 5V DC to pads marked IN+ and IN- on the left-hand side of the module
2. Connect cell to charge to B+/B- pads on the right-hand side of the module.
3. A load (something for the battery to power) can be connected to the OUT+/OUT- pads on the right-hand side
4. Important! Disconnect load when charging
5. The red LED indicates charging in progress, green LED indicates charging has finished.
6. Never charge your battery at a rate greater than 1C.

This is Male To Male Jumper Wires (10cm) - 40 Pieces pack. A very Flexible and easily detachable cable to the no. of wires according to your requirement. It has 1Pin male to the 1pin male header with both ends. Also, it is compatible with 2.54 mm mil spacing pin headers.

This cable is an electrical wire or group of them in a cable with a connector or pins at each end, which is normally for interconnecting the components of a bread board or other prototype or test circuit, internally or with other equipment or components, without soldering.

Individual Dupont Cables are fitted by inserting their end connectors into the slots provided in a breadboard, the header connect or of a circuit board, or a piece of test equipment.
