This is a 5V 8-Channel Relay interface board, Be able to control various appliances and other equipment with large current. It can be controlled directly by Micro-controller (Raspberry Pi, Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).
The protective case is made by high grade acryl, which provides excellent protection, with fashion appearance. This is unique design for relay module with pin lekage, which provides easy connection to other components.
5V 8-Channel Relay interface board and each one needs 15-20mA Driver Current
Equipped with high-current relay, AC250V 10A ; DC30V 10A
Standard interface that can be controlled directly by microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic)
This is Sainsmart 4.3 inch TFT LCD module,It is 100% compatible with the normal MCU like ARM AVR PIC and 8051,especially on arduino family such as arduino due and arduino mega2560(R3).The module uses the LCD controller Chip SSD1963 with 4.3 inch LCD including the touchscreen.
This is a 2.4GHz Wireless Complete Module. Wireless communication become extremely easy.
Auto-acknowledge and auto-retransmit abilities
Internal filtering results in high margins of meeting RF regulatory standards. The module's radio uses Gaussian Frequency-Shift Keying (GFSK) modulation as well as fast Automatic Gain Control (AGC).
The module includes an Interrupt Request (IRQ) pin which can be used to wake the host microcontroller, (ex: Arduino), from sleep when the module receives a transmission providing great power conservation in battery devices.
