## Description

The Crowduino UNO ESP8266 combines an Arduino UNO-compatible microcontroller with an onboard ESP8266 WiFi module in a single, compact board. Instead of wiring a separate WiFi shield or module, you get integrated wireless connectivity right out of the box. Built around the ATmega328 running at 16 MHz, this board maintains full compatibility with Arduino UNO shields and sketches while adding 802.11 b/g/n WiFi via the ESP8266. The two processors communicate over a high-speed UART at 115200 bps, making it straightforward to add wireless data transmission, remote control, and IoT connectivity to your projects. Key Features ATmega328 Microcontroller – 16 MHz clock, 32 KB flash (0.5 KB bootloader), 2 KB SRAM, 1 KB EEPROM Integrated ESP8266 WiFi – 802.11 b/g/n with WiFi Direct (P2P), soft-AP support, and integrated TCP/IP stack 14 Digital I/O Pins – 6 with PWM output, 40 mA per pin 8 Analogue Input Pins – For sensor and signal reading UNO R3 Form Factor – Compatible with standard Arduino shields High-Speed Serial Link – 115200 bps default baud rate between ATmega328 and ESP8266 +19.5 dBm Output Power – Strong WiFi signal in 802.11b mode Specifications Operating Voltage: 5 V Input Voltage: 7–12 V (6–15 V limit) 3.3 V Pin Current: 50 mA Dimensions: 70.0 × 55.0 × 11.8 mm Ideal For IoT and smart home projects Remote monitoring and data logging WiFi-enabled robotics Wireless sensor networks Package Contents 1× Crowduino UNO ESP8266 V1.1 board Resources Elecrow Wiki – ESPduino Guide Eagle Design Files
