Hi-07S is a Wi-Fi module developed by Ai-Thinker. It can be widely used in intelligent terminal products related to the IoT, such as smart homes, smart security, and smart cities. Hi-07S module is equipped with Hi3861V100 core processor chip. The chip is a highly integrated 2.4GHz low-power SoC WiFi chip that integrates IEEE 802.11b/g/n base band and RF circuits. The RF circuit includes power amplifier PA, low noise amplifier LNA, RF balun, antenna switch and power supply Management and other modules. It supports 20MHz standard band width and 5MHz/10MHz narrow bandwidth, and provides a maximum physical layer rate of 72.2Mbit/s. The WiFi baseband of the chip supports Orthogonal Frequency Division Multiplexing (OFDM) technology, and is backward compatible with Direct Sequence Spread Spectrum (DSSS) and Complementary Code Keying (CCK) technology, and supports various data in IEEE 802.11 b/g/n protocols rate. The Hi3861V100 chip of the Hi-07S module also integrates a high-performance 32-bit microprocessor, a hardware security engine, and a wealth of peripheral interfaces. The peripheral interfaces include SPI, UART, I2C, PWM, GPIO, and multiple ADCs. It also supports high-speed SDIO2.0 Slave interface, the highest clock can reach 50MHz; The chip has built-in SRAM and Flash, which can run independently, and supports running programs on Flash. The Hi-07S module supports Huawei Lite OS and third-party components, and provides an open and easy-to-use development and debugging environment.
