Study Notes
Internet of Things Development Boards
- IoT development boards are tools for creating and prototyping IoT applications.
- These boards have various characteristics which makes them suitable for diverse IoT projects.
- Processing Power: Many IoT development boards come with microcontrollers or microprocessors that vary in computational power.
- Connectivity Options: Commonly support multiple connectivity options such as Wi-Fi, Bluetooth, Zigbee, LoRa, and cellular (4G/5G).
- Size and Form Factor: Boards can range from small modules like the ESP8266 to larger ones like the Raspberry Pi.
- Development Environment and Software Support: Boards provide support for various development environments (IDEs) and programming languages.
- Sensors and Actuators Compatibility: The boards can be used for integration with various sensors (temperature, humidity, motion) and actuators (motors, relays).
Raspberry Pi
- Raspberry Pi is a low-cost, credit-card-sized microprocessor computer.
- It can connect to a computer monitor or TV and uses a standard keyboard and mouse.
Arduino
- Arduino UNO is a microcontroller board based on the ATmega328P.
- It features 14 digital input/output pins (including 6 PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.
NodeMCU ESP8266 CH340
- The NodeMCU is an open-source firmware and development kit that helps you to prototype your IoT product with wifi controlling.
- The Development Kit based on ESP8266, integrated GPIO, PWM, IIC, 1- Wire, and ADC all in one board.
- Board is a leading edge low-cost Wi-Fi technology and a super simple way to complement existing Arduino projects or any development board that has I/O pins available.
