MELIFE 2 Pack ESP32 ESP-32S Development Board
- Low power consumption
- Supports three modes: AP, STA, and AP+STA
- Works perfectly with the Arduino IDE
- It does not come with a cable
The Intel MELIFE 2 Pack ESP32 ESP-32S Development Board is perhaps the best choice for entry-level education environments.
The device is designed to build students’ technology skillsets through hands-on projects in coding.
MELIFE 2 Pack ESP32 ESP-32S Development Board features a Bluetooth Dual Cores Microcontroller Processor Integrated with ESP32s Antenna.
- Based on ATmega32u4 and W5500 Ethernet chip
- High-speed network communication
- A professional power regulation chip for working under complex envirnoments
- Delays in connecting at times
The W5500 Ethernet with POE IOT Board is compatible with the ATmega32u4 and W5500 Ethernet chip, which is quite useful to most IoT projects.
It provides an easier Internet connection to embedded systems while enabling users to have Internet connectivity in their applications.
The WOL (Wake on LAN) and power-down feature mode reduces the power consumption significantly. Moreover, the W5500 Ethernet is also compatible with most of Arduino compatible shields and sensors.
- Built-in USB to Serial UART adapter
- Two diode-protected power inputs
- Onboard GPIO, PWM, ADC, I2C, and 1-Wire
- The quality could be improved
One major advantage of this board is that you can get started building your internet-connected project in seconds.
All you need to do is plug the board into a USB port, download the programming app (Arduino IDE), and you’ll be ready to start writing code.
