The D1 Mini provides high performance for its size, significantly outperforming standard microcontrollers like the Arduino Uno in computational tasks. Specification ESP-8266EX Operating Voltage 3.3V (5V input supported via regulator) Clock Speed 80 MHz / 160 MHz Flash Memory Digital I/O Pins 11 (all support PWM, I2C, and interrupts, except D0) Analog Input 1 (Max 3.2V input) Dimensions 34.2mm x 25.6mm; ~3g Pinout and Connectivity Despite its size, the exposes essential communication interfaces: I2C : Primarily uses D1 (SCL) and D2 (SDA) . Serial : TX and RX pins for UART communication.

(originally by ) is a compact, Wi-Fi-enabled microcontroller based on the ESP8266EX chip. It is widely favored for Internet of Things (IoT) projects due to its tiny footprint, affordability (often under $5), and extensive ecosystem of stackable "shields". Technical Specifications
