Espressif teased us about a successor to ESP8266 a few months ago that would support both WiFi and Bluetooth Low Energy, and John Lee, working for Espressif Systems, has now sent a letter to ESP8266 developers announcing the new wireless SoC with two Tensilica L108 cores and called ESP32. Espressif ESP32 key improvements over ESP8266: Faster WiFi – Wifi has been upgraded to support HT40 speed (144.4 Mbps) and has a new RF architecture to simplify the application schematics Bluetooth Low Energy and Classic Dual core processor – 2x Tensilica L108 processors clocked at up to 160 MHz Low Power Mode Improvements – ADC conversions, level thresholds, etc.. can now be performed in deep sleep Peripherals – Capacitive touch, ADCs, DACs, I2C. UART, SPI, SDIO, I2S, RMII, PMW, etc… but no USB. More RAM – ~400 KB on-chip RAM Security – Hardware accelerated AES and SSL, and more undisclosed improvements. […]
