Product description
The ESP-12S is a compact and cost-effective WiFi module designed for IoT applications. It is based on the ESP8266 chip and features 4MB flash and a built-in WiFi transceiver. The module is easy to hand solder and has improved RF performance compared to previous versions such as ESP-07 and ESP-12E.

The ESP-12S drops the bottom row of pads compared to the ESP-12F (these pads can't be used for connection under normal circumstances anyway), it is also a slightly smaller module. All other features are identical to the ESP-12F.


Features:

  • ESP8266 32-bit microcontroller
  • 4MB flash memory
  • WiFi connectivity
  • Multiple communication interfaces: UART, SPI, I2C
  • Supports station and soft-AP wireless modes
  • Low power consumption
  • Improved RF performance compared to previous versions
  • Compatible with Arduino, Micropython, Tasmota and ESPHome
  • Easy to hand solder
