The ESP32-D0WD features dual microprocessors, one for normal operation, and one for low-power sleep mode, in an ultra-compact 5 x 5 mm package. The Bluetooth® Low Energy (BLE) Link Layer discovery process consists of devices which use advertising channels to find each other, with one device advertising and another device scanning. ILI9341 display over SPI with DMA. 0, dedicated DMA, Ethernet MAC interface, Motor PWM, LED PWM (16 channels) etc. Now, I am working projeck on NXP kinetis microcontroller without WiFi (only ethernet) and I am thinking about change this to ESP32. 2 YEARS OF SIGFOX CONNECTIVITY INCLUDED. ESP32 contains two I2S peripherals.
