General Description

AcSiP Technology Corp. introduces a low-cost and low-power consumption IoT module.This stand-alone module is an operating system designed for wearable or samrt home devices with smart connection and cloud application/services.

AI7697HD is a highly integrated SIP module which features an application processor, a low power 1x1 11n Dual-band Wi-Fi subsystem, a Bluetooth subsystem, and a Power Management Unit. The application processor subsystem contains an ARM Cortex-M4F MCU, which has many peripherals, including UART, I2C, SPI, I2S, PWM, IrDA, and auxiliary ADC. AI7697HD also includes embedded SRAM/ROM and an external 4MB serial flash.

Developers can implement their IoT applications using this RTOS SDK and there is a example of AWS access for cloud service feature to present  big data monitor scenario.
