ESP-01D

The ESP-01D WiFi module, developed by Ai-Thinker, features the ESP8285 as its core processor. The ESP8285 integrates the industry-leading Tensilica L106 ultra-low-power 32-bit microcontroller in a compact package, with a 16-bit reduced instruction set. It supports clock speeds of 80 MHz and 160 MHz, RTOS support, and integrates Wi-Fi MAC/BB/RF/PA/LNA.

The ESP-01D WiFi module supports standard IEEE802.11 b/g/n protocols and a complete TCP/IP protocol stack. Users can use this module to add networking functionality to existing devices or build standalone network controllers. The ESP8285 is a high-performance wireless SoC that provides maximum practicality at the lowest cost, offering unlimited possibilities for embedding WiFi functionality into other systems.
