Details Information

Introduction

3121N-IEE is a fully integrated power carrier (PLC) CCO communication module, which provides a weak current interface and a strong current interface through pin header connectors. Weak current interface for power supply input, UART communication and reset signal connection;The strong current interface is used for PLC communication of three-phase power line. The module can be widely used in smart street lights, energy management, smart meter reading and other application scenarios.

The module size and interface conform to the State Grid QGDW 1375.2-2019 standard.

The module is based on HiSilicon PEO211 chipset, integrated high-speed/low-speed multi-mode power line carrier communication modem and ARM Cortex-M3 processor. The PEO211 chip supports P1901.1 and supports OFDM/FSK modulation.

The onboard external Line-Driver improves the transmit signal strength and can meet the needs of customers for longer distances.

Equipped with Huawei IoT open source operating system LiteOS, it provides a more open development environment and a faster and safer operating system.
