Introduction

Hi-07SL is a Wi-Fi module widely used in IoT-related smart terminal products such as smart home, smart security, and smart city applications. The module is powered by the Hi3861LV100 core processor chip — a highly integrated 2.4GHz low-power SoC Wi-Fi chip that integrates IEEE 802.11b/g/n baseband and RF circuitry, including PA, LNA, RF balun, antenna switch, and power management modules. It supports 20MHz standard bandwidth and 5MHz/10MHz narrow bandwidth, delivering a maximum physical layer rate of 72.2Mbit/s. The Wi-Fi baseband supports OFDM technology with backward compatibility for DSSS and CCK, supporting various data rates defined in the IEEE 802.11b/g/n protocol. Like the Hi3861LV100 chip, the Hi-07SL module features a high-performance 32-bit microprocessor, hardware engines, and a rich set of peripheral interfaces including SPI, UART, I2C, PWM, GPIO, and multi-channel ADC, along with a high-speed SDIO 2.0 Slave interface with a maximum clock of 50MHz. The chip integrates on-chip SRAM and Flash, enabling standalone operation with support for executing programs directly from Flash. The Hi-07SL module supports Huawei LiteOS and third-party components, and comes with an open, easy-to-use development and debugging environment.
