Arduino Compatible Boards & Modules

Arduino Compatible Electronics
Arduino compatible boards and modules provide flexible alternatives to official Arduino hardware while maintaining full compatibility with the Arduino IDE, libraries, and ecosystem. These microcontroller boards use the same ATmega and ARM processors, accept standard Arduino shields, and run identical sketches.

Microcontroller Boards
Arduino compatible development boards offer various form factors and specifications. Options include Uno R3 clones with ATmega328P processors, Mega-compatible boards with ATmega2560 chips for projects requiring more I/O pins, and Nano-sized boards for compact builds. Many feature USB-to-serial chips like CH340G or CP2102 for programming and serial communication.

Shields and Expansion Modules
Compatible shields and expansion boards stack directly onto Arduino form factor boards. Motor driver shields control DC motors and stepper motors. Ethernet and WiFi shields add network connectivity. Sensor shields provide standardized connections for multiple sensors. LCD and TFT display shields enable visual interfaces.

Sensors and Input Modules
Sensor modules designed for Arduino include temperature sensors (DHT11, DHT22, DS18B20), motion sensors (PIR, ultrasonic), light sensors (LDR, BH1750), and environmental sensors. Most use I2C, SPI, or simple analog/digital interfaces with existing Arduino libraries.

Communication and Interface Modules
Communication modules extend Arduino projects with Bluetooth (HC-05, HC-06), WiFi (ESP8266, ESP32), RF transceivers (nRF24L01), and GPS receivers. Interface modules include relay boards, level shifters, and power supplies compatible with Arduino voltage requirements.

Programming and Compatibility
All Arduino compatible products work with the Arduino IDE and accept standard Arduino sketches. Pin layouts match official Arduino boards for shield compatibility. Most use standard bootloaders and support programming via USB or ICSP headers.
