1. Production Overview
The OSL-ESP8266M4 Wi-Fi Module is designed by Osmartlink
Technology Co., Ltd. The module's MCU ESP8266 integrates the
industry-leading Tensilica L106 32-bit MCU and ultra-low-power
16-bit RSIC in the smaller size package.The CPU clock speed is
80MHz.It can also reach a maximum value of 160MHz.Real Time
Operation System(RTOS) is enabled. And it integrates Wi-Fi MAC/
BB/RF/PA/LNA and On-board antenna.
The module supports standard IEEE802.11b/g/n protocol and integrated TCP/IP
stack.The module can be used to add networking function, and it also can be used to build an
independent network controller.
