1.1 Overview
BiTrend™ Essentialis the industrial leading 2.4Ghz 802.11 b/g/n embedded Wi-Fi module which delivers unmatched performance and codeless development in a compact package, providing a quick, easy and cost effective way for developers and manufacturers to add Wi-Fi connectivity for home automation, lighting control, energy efficiency and other IOT applications.
BiTrend™ Essential family combines a 2.4Ghz 802.11 b/g/n radio transceiver with a 32-bit microprocessor and embedded with MAC, baseband processing and optimized Wi-Fi network stack. It is an ideal solution for developers and manufacturers with limited RF and embedded programming expertise as it significantly reduces RF design time and removes the burden of testing and certification.
Benefitted from BroadLink’s turn-key solution, BiTrend™ Essential is an ideal solution for developers with limited Wi-Fi or RF expertise or for those seeking faster time to market. It
reduces RF design time and removes the burden of testing and certification. BiTrend™ Essential
is fully compliant with IEEE 802.11 b/g/n standard and certified with CE, FCC and RoHS.
BiTrend™ Essential is a highly integrated Wi-Fi SoC(system on Chip) single chip, which supportsIEEE802.11b/g/n single stream, providing GPIO for intelligent control, and UART interfaces for device communication.
BiTrend™ Essential has 8Mbits flash and integrates power amplifier, low noise amplifier, and RF switch to reduce the module size and RF design capability required. And also integrate power manage unit for single 3.3V power source for cost effective design.
BiTrend™ Essential 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 WT1SBSL is an ideal solution for embedded device to enable networking service with minimized design effort.
