ESP32-S3 A7670E 4G Development Board with Cat-1 Modem and GNSS

✅ Send data over mobile. The A7670E modem carries the feed when local Wi-Fi is out of reach.

✅ Know where it is. GNSS support puts position data into the application you write.

✅ Power it your way. USB, a battery holder or an external battery each feed the board.

✅ Add your own parts. Camera, microSD and pin-header connections leave room for extra functions.

A cellular base for your own IoT build

A development platform that pairs an ESP32-S3 controller with an A7670E Cat-1 modem for projects that need a mobile network. Camera, microSD and pin-header connections sit alongside GNSS position data, and power can come from USB or a 3.7-4.2 V battery input. Check the network bands and service terms before you build.
