The WE866E4-P is a fully integrated dual band, dual mode, combo Wi-Fi (802.11 a/b/g/n) / Bluetooth Low Energy (BLE) 5.0 module with an extremely small footprint (285 sq mm) that provides an easy, cost-effective way for manufacturers to add wireless connectivity to their products. Module comes up with an integrated tri-core system-on-chip, with dedicated CPU’s for IoT application, Wi-Fi and BLE. The IoT application processor runs on ARM Cortex-M4F @128 MHz with 300KB of dedicated SRAM. Module also integrates 4MB of internal flash with wide array of peripherals (SDIO, SPI, UART, ADC, PWM, GPIO, I2S, I2C, USB-for manufacturing only).
This module also provides a low-cost, high-speed serial to Wi-Fi/BLE connection to an embedded design built on an 8/16/32-bit microcontroller, through UART, SPI, or SDIO interfaces.
