This is Tiny RTC Real Time Clock DS1307 I2C IIC Module for Arduino. It contains a DS1307 real-time clock IC with a backup battery. It’s one of the easiest to use RTCs out there, with Arduino and other libraries or simply use I2C commands to set and retrieve the time and date. Includes a lithium coin cell battery which should be good for four years at least.

Along with the DS1307 real-time clock, the module also has an Atmel 24C32 EEPROM chip which is handy for storing data without worrying about power loss. There is also space on the board to solder your own DS18B20 temperature sensor.

This battery-powered clock allows you to keep a reasonably accurate time even when your Arduino is powered off.  It is very useful in data logging and other time-sensitive applications. The device uses I2C to communicate with your Arduino.

Note: Battery is not included in the package, you need to buy it separately.

• Evaluation board for A7670C, A7670E & A7670SA modules made by SIMCOM
• Main supply can take standard 12V DC adapter
• The device supports a LiPo battery input.
• Device supports 4G LTE-CAT1 network only.
• A7670C - Asian band 4G LTE CAT1 module
• A7670E - European band 4G LTE CAT1 module

NOTE : SMA connectors and headers are not soldered on board by default.  

This is a 4G GSM module development board which can be used with Arduino and Raspberry Pi kind of development boards for evaluating the features of SIMCOM A7670 modules. 

This 4G GSM Modem supports 9VDC to 42V DC voltage input on the DC jack input. The extended operating range helps in directly connecting the modem to different power sources like lead acid battery, DC adapters and EV supply. 

There is on board IO level translator for converting the 1.8V UART TX and RX lines of modem to MCU IO voltage level connected to VTRANS pin. 

The A7670x-LASS module has support for Analog audio compared to its predecessor 4G modules like SIM7600 which only had PCM audio interface. You can directly connect a electret MIC to this board as bias circuit is already provided. However for Speaker output you need to use a headphone or amplifier as the signal is weak and needs to be amplified. 

A7670C/A7670E/A7670SA is a very good 4G alternative for 2G modules like SIM900, SIM900A, SIM800 & SIM808. It comes at a very low price and can serve in as a drop in replacement.

• Rectification: Non-Synchronous Rectification
• Input Voltage Range: 3V ~ 32V
• Output Voltage RAnge: 5V ~ 35V (Note: If you want to get the max voltage, you should make the input current as least 3A)
• Input Current: 4A (max), no-load 18mA (5V input, 8V output, no-load is less than 18mA. Higher the voltage, the greater the load current.)
• Conversion efficiency: <94% (greater the pressure, the lower the efficiency)
• Switching frequency: 400KHz
• Output Ripple: 50mV (the higher the voltage, the greater the current, the greater the ripple)

When using these modules remember that the output current will be a lot less than the input current, (remember - W = VA). For example, if you have a 10V output at 1A from a 5V input, the input current will be around 3.6A. The real-life maximum amount of power you can get out of these things is around 10W. 

Output current is greater than 2.5A (or output power greater than 10W) to work long hours, please add heat sink.

Maybe you''re making a piece of art with tons of moving parts, or you need to drive a ton of LEDs with precise PWM output. Your microcontroller has a limited number of PWM outputs, and you find yourself running out! Need to run more than 16 PWM outputs? No problem. Chain together up to 62 of these beauties for up to an outstanding 992 PWM outputs.

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 finished.

Furthermore, when the battery voltage drops below 2.4V the protection IC will switch the load off to protect the cell from running at too low of a voltage and also protects against over-voltage and reverse polarity connection (it will usually destroy itself instead of the battery) however please check you have it connected correctly the first time.
