ESP8266 SoCs
- 32-bit MCU & 2.4 GHz Wi-Fi
- High-performance 160 MHz single-core CPU
- +19.5 dBm output power ensures a good physical range
- Sleep current is less than 20 μA, making it suitable for battery-powered and wearable-electronics applications
- Peripherals include UART, GPIO, I2C, I2S, SDIO, PWM, ADC and SPI
