Product Features :
  • 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.
