Octopus Electronic Bricks, you can use them to build electronics projects just as easy as piling bricks. By using Octopus electronic bricks, you may connect Arduino / Freaduino compatible boards easily with various digital, analog and I2C/Uart interfaces. These the breadboard-less firm connection are prepared to extensive modules like poteniometers, sensors, relays, servos ... even buttons, just plug and play.
OCTOPUS Real-time Clock is a clock module which can achieve counting for year, month, day, hour by using the DS1307 clock chip.This chip has lots of merits, low power supply, with 56 bytes of non-volatile RAM clock calendar full BCD code real-time clock chip, the address and data via a two-wire bidirectional serial bus transmission, providing seconds, minutes, hours and other information , automatically adjusting the number of days in each month. And more surprisingly, the chip also equip with the function of leap year compensation. Chip has a built-in power-sense circuit, brownout detection, and battery switching function.

Jargon buster
Plain-language definitions for the technical terms used above.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- RAM
- RAM (random-access memory) is fast, temporary memory a device uses for working data while it is running; in its common volatile form, its contents are lost when power is removed. Some devices offer a mode that applies settings to RAM only, which is handy for testing changes temporarily because they are not stored permanently and disappear at power-off.
- RST
- RST (reset) is a control pin used to restart or reinitialise a device to a known state. Connecting an RST pin to a microcontroller lets the host reset the device, which can help with reliable start-up or recovery.
- UART
- UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
- VCC
- VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
