1. Description
AcSiP Technology Corp. introduces a low-cost and low-power consumption IOT module, AI7681H. The
AI7681H integrate Wi-Fi single chip, which supports IEEE 802.11b/g/n stream, providing GPIO for intelligent
control, and UART interfaces for device communication.
The AI7681H integrate chip antenna and 8Mbits flash to reduce customer platform size. And also integrate
power manage unit for single 3.3V power source for cost effective design.
The AI7681H embedded 32-bit RISC MCU for 802.11b/g/n drivers, supplicant, TCP/IP protocol stack, and
networking applications, can be operated in station mode and softAP mode. The AI7681H is an ideal solution for
embedded device to enable networking service with minimized design effort.
