Product Features :
- Evaluation board for A7672S module made by SIMCOM
- Main supply can take standard 5V DC adapter
- The device supports a LiPo battery input.
- Device supports 4G LTE-CAT1 network with 2G dualband.
- A7672S – Indian band 4G LTE CAT1 module
- A7672E – European band 4G LTE CAT1 module
- Inbuilt GNSS , antenna to be connected to U.FL connector
- Inbuit Bluetooth 4 , antenna to be connected to U.FL connectorNOTE : SMA connectors and headers are not soldered on board by default.
This is a 4G GSM module board which can be used with Arduino and Raspberry Pi kind of development boards for evaluating the features of SIMCOM A7672 modules. Since the A7672 FASE variant supports GNSS and Bluetooth, you can use it as a good develpment platform for developing GPS tracker products.
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.
In addition to supporting 4G-LTE-CAT1 network it has 2G fallback which helps to switch to 2G network in rural areas where 4G is still not yet deployed.
A7672 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.
NOTE : No MIC & SPK pins provided
