*GitHub : https://github.com/rdiot/rdiot-s029.git

* Specs

DS1307 I2C real-time clock chip (RTC)

24C32 32K I2C EEPROM memory

The using LIR2032 rechargeable lithium battery with charging circuit

Solve the problem DS1307 with backup battery can not read and write.

Fully charged, it can provide the DS1307 timing 1.

Compact design, 27mm * 28mm * 8.4mm

Leads to the a DS1307 clock pin, to provide the clock signal for the microcontroller.

Other I2C devices can be cascaded

8 Channel Solid State Relay Module [S168]

https://www.youtube.com/watch?v=zitAS2YxezE

* Specs

Description:

5V Omron solid state relays 240V 2A, output with resistive fuse 240V 2A

Size: 103*53*21mm/4.05*2.08*0.82"

The input power supply: 5V DC (160mA)

The input control signal voltage:

(0-2.5V low state relays ON)

(3.3-5V state high relay OFF)

2.54cm pin and blue KF301 terminals connected to the control line is more convenient

Module interface:

Input section:

DC +: positive power supply (relay voltage power supply)

DC-: connect power negative

CH1: 1 signal to trigger the end of the relay module (low level trigger valid)

CH2: 2-way relay module signal triggering end (low level trigger valid)

CH3: 3 relay module signal triggering end (low level trigger valid)

CH4: 4-channel relay module signal triggering end (low level trigger valid)

CH5: 5-way relay module signal triggering end (low level trigger valid)

CH6: 6-way relay module signal triggering end (low level trigger valid)

CH7: 7-way relay module signal triggering end (low level trigger valid)

CH8: 8-channel relay module signal triggering end (low level trigger valid)
