Details Information

Introduction

3121N-ISF is a fully integrated power carrier (PLC) communication module with ultra-miniature size, compact structure and simple wiring. It can be widely used in various PLC instant communication application scenarios such as intelligent street lamp, intelligent home, intelligent parking, central air conditioning and ubiquitous power IoT terminal equipment.

3121N-ISF is based on HiSilicon PSO211 chipset, which integrates high-speed/low-speed multi-mode power line carrier communication modem and ARM Cortex-M3 processor. The PSO211 chipset supports P1901.1 and supports OFDM/FSK modulation.

3121N-ISF provides rich peripheral interfaces such as UART, PWM, GPIO, I2C, SPI, ADC, etc., and integrates a built-in Line-Driver. 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
