Introducing the ESP-01s 2023 version, featuring the latest ESP8285 MCU. This new iteration maintains full compatibility with the previous ESP-01 model, which used the ESP8266EX MCU. The ESP8266EX has been discontinued by Espressif Systems and replaced with the advanced ESP8285 MCU.

One of the key advantages of the ESP8285 is the built-in 1MB flash memory within the chip itself. This eliminates the need for an external SPI flash, resulting in lower power consumption due to fewer external components. Additionally, the ESP8285 has addressed the well-known Wi-Fi bugs present in the ESP8266EX, providing more secure and reliable Wi-Fi connections.

The 2023 ESP-01s remains fully compatible with its predecessor. You have the flexibility to utilize the AT-Command set, which allows the ESP-01s to function as a Wi-Fi adapter for other MCUs. Alternatively, you can leverage the power of the IDE and write C code directly for the ESP-01s, simplifying the development process.

With the ESP-01s 2023 version and its upgraded ESP8285 MCU, you can enjoy enhanced functionality, improved power efficiency, and secure Wi-Fi connections while maintaining seamless compatibility with previous ESP-01s models.

Experience the power of complete and self-contained Wi-Fi networking capabilities. The ESP8285 can operate as a standalone application or seamlessly integrate as a slave to a host MCU. When hosting the application, it boots up quickly from the flash, thanks to its integrated high-speed cache, enhancing system performance and optimizing memory usage.

Not just limited to standalone use, the ESP8285 can also serve as a Wi-Fi adapter for any microcontroller design. With flexible SPI/SDIO or UART interfaces, it seamlessly integrates into your existing setup, expanding its capabilities.

The ESP8285 comes packed with integrated features, including antenna switches, RF balun, power amplifier, low noise receive amplifier, filters, and power management modules. Its compact design minimizes the PCB size, eliminating the need for excessive external circuitry.

But that's not all! This powerful board also integrates Tensilica's L106 Diamond series 32-bit processor and on-chip SRAM, taking your projects to new heights. With GPIOs for external sensor and device interfacing, the possibilities are endless.

To make development even easier, the Software Development Kit (SDK) provides sample codes for a variety of applications, giving you a head start on your IoT journey.
