PT7686W-S** series are a low-cost, low-power consumption and highly-integrated embedded 1X1 11b/g/n single-band Wi-Fi module specially designed for IOT (Internet of Things) market. This module adopts the SOC chip from MTK which contains an ARM Cortex-M4F MCU application process running at 192MHz, Wi-Fi subsystem and power management unit (PMU).

PT7686W-S** series have embedded 384KB SRAM, 32KB L1 cache, 4MBs pseudo SRAM with half sleep mode current: 10μA and 4MB serial flash, running at RTOS environment. It also support many peripherals which including SPI, SDIO, I2S, I2C, UART, PWM and auxiliary ADC. This is perfectly suitable for all variety of applications in the IOT market.

A dedicated high-performance 32-bit RISC CPU N9 up to 160MHz clock speed is implemented to achieve robust Wi-Fi connection with support variety of security encryptions.PT7686W-S** series compliant with IEEE 802.11 b/g/n standard with 20MHz and 40MHz bandwidth and up to 150Mbps data rate.

Highly integrated PT7686W-S** series modules enable easy configurations, all types of power saving mode to maximize battery life, seamless roaming capabilities and advanced security. It can be also interact with different access point (AP) from different vendors.

A high-performance printed antenna is designed on the module to obtain low-cost, easy to use and compact module size. PT7686W-S** series modules also provide several RF connector variants (ex. PT7686W-SC*, PT7686-SA*, PT7686-SP*) that allow customers to use external antenna when it is required.
