M12-C Series

Battery Powered IoT Node / STM32L1 Based

The M12-C Series is a lightweight, battery-powered ESP32 controller designed for standalone deployments where grid power is unavailable. Powered by 4 x AA batteries, this controller can operate autonomously in remote locations, powering both itself and connected low-power sensors.

Engineered for energy efficiency, the M12-C Series supports low-power communication technologies such as LoRa, NB-IoT, Zigbee 3, and GSM/LTE, enabling reliable long-distance data transmission with minimal energy usage.

Key Features

ESP32 dual-core microcontroller l Operates on 4 x AA batteries l Supports GSM/LTE, NB-IoT, LoRa, and Zigbee 3 l Optimized for low-power consumption l Supports wireless communication up to several kilometers l Flexible integration with remote sensors and field devices l Programmable via Arduino IDE and ESP-IDF

Price:

Price range: $90.00 through $116.00
