It is a 5V 8 Channel Relay Module. The relay normally open interface maximum load: AC 250V/10A, DC 30V/10A. It has a trigger current of 5mA, and module working voltage of DC 5V. Each channel of the module can be triggered by a jumper to set a high level or a low level. Fault-tolerant design, even if the control line is disconnected, the relay will not move. With status indicator: power (green), 6-channel relay status indicator (red). All module size interfaces can be directly connected through the terminal block, which is convenient and practical.

Features:

1. The 8550 transistor drive, driveability.
2. A fixed bolt holes for easy installation.
3. It has a relay status indicator led Power LED(Green), 8 relay status indicator LED(Red)
4. Relay control interface by single-chip IO.
5. Low-level suction close, high-level release.
6. Easy to use, simple 3 line structure.

Package Includes:

1 x 5V 8 Channel Relay Module.

TEA5767 Stereo FM Radio Module with Detachable Antenna is made using TEA5767, a single-chip electronically tuned stereo FM radio for low voltage applications. It has fully integrated Intermediate Frequency (IF) selectivity and FM demodulator.

The radio is completely adjustment-free and is very easy to use as it requires only minimum external components. This module can be tuned to many FM bands and it can be easily interfaced with Arduino Boards, Raspberry Pi, and Microcontrollers via the I2C interface.

The Module has reverse polarity protection diode and power output filtering sensor. It can be Directly plugged to the antenna interface. Additionally, it has a Multi capacitor combined filter and Blue LED power indicator for On-Off status.

This is a 5V 4-Channel Relay interface board, be able to control various appliances and other equipment with large current. It can be controlled directly by Microcontroller (for Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).

Features:

1. 5V 4-Channel Relay interface board and each one needs 15-20mA Driver Current.
