IoT Modules with MCU
PLC: UART/GPIO/PWM/I2C/SPI
Product Name
PEO211 PLC-IoT Module 3121N-IEE
PEO211
0.5-5.7MHz
UART/PLC
MCU: Cortex M3, 200MHz
92.8 x 63.8mm
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.
Features
CPU and Storage Performance
Hisilicon Hi3921E high-performance Cortex-M3 processor, working frequency 200MHz.
Embedded SRAM 256KB.
Plug-in 2MB Flash.
PLC Physical Layer Features
Realize a subset of the IEEE 1901.1 standard. For chips that also use this subset, they can achieve interconnection and interoperability.

Adopt OFDM technology; support BPSK, QPSK modulation mode.
Support FEC and CRC functions, powerful denoising and error correction capabilities.
PLC MAC Features
Support TDMA and CSMA/CA, and provide conflict avoidance mechanism.
Support data segmentation and reorganization to improve transmission efficiency.
Support data retransmission mechanism.
Support 4-level QoS to meet different business service quality requirements.
PLC Networking Features
Supports automatic and fast networking, typical 200-scale, 2-level network scenarios, complete fast networking in 10s, and support fast communication.
Support dynamic routing, multi-path addressing.
Other interfaces
UART
Communication indicators
