Overview

This is a 4G GSM module development board that can be used with Arduino, Raspberry Pi, and other microcontroller platforms
for evaluating the features of SIMCom A7670 modules.
Its wide input supply range (9V–42V DC) allows flexible power options including lead-acid batteries, DC adapters, and EV supplies.

The onboard IO level translator converts the 1.8V UART TX/RX lines of the modem to MCU I/O voltage via the VTRANS pin.

Band Support

A7670C-LASS: Optimized for Asian regions (India, Indonesia, Malaysia, China, Taiwan, Thailand, Sri-Lanka, Bangladesh, Myanmar, Nepal).
Supported Bands: LTE-FDD B1/B3/B5/B8, B34/B38/B39/B40/B41
GSM fallback: 900/1800

The A7670 series is a cost-effective 4G alternative to SIM900, SIM900A, SIM800 & SIM808, making it suitable as a drop-in replacement.
