Description
The ESP32-S is an Original ESP32 series module from Ai-Thinker. This wireless module based on ESP32, supports WiFi and Bluetooth 4.2, with built-in 32Mbit Flash, in the SMD38 package. There’re also onboard PCB antenna and metal shield. In short, it’s a small form factor and fairly high cost-effective wireless module.
With the pre-flashed AT firmware, you can control the module through UART AT commands easily. The module integrates MCU inside, supports other developments like Lua/Micropython/Arduino to achieve flexible and fast prototyping, make it easy to integrate the module into IoT applications.
Ai-Thinker’s ESP32-S WiFi+BT SoC Module has a highly competitive package size and ultra-low power technology. Esp32-S can be widely used in various networking, for home automation, industrial wireless control, baby monitors, wearable electronics products, wireless position sensing devices, wireless positioning system signals, and other networking applications. Esp32-S is packaged in SMD, through the standard SMT equipment to achieve rapid production of products, to provide customers with high reliability of the connection, especially for Automation, large-scale, low-cost modern production methods, It’s suitable for all kinds of Internet of things hardware terminal occasions.
