- It is 100% compatible with Arduino UNO R3 program, expansion shields, IDE.
- Especially added 500mA resettable fuse ​onboard to protect power supply from the USB port and the DC jack at the same time.
- Use multi-color female header so that the interface is easy to identify and particularly noticeable.
- Use Through Hole Mount type B USB connector, consistent with Arduino UNO R3, ruggedness and long service life.
- Leads out more GND, 5V pins, UART serial interface and I2C interface, so it is more convenient to connect it to peripheral modules without additional IO expansion shield.
- You can burn the program with the type A male to type B male cable.
- Onboard 5V and 3.3V voltage regulator circuit.
- Onboard DC jack socket and it can be powered by an external battery so it allows you to show your projects in the outdoor without the PC.
- This board is ideal for learners want to learn Arduino and make creative projects.
- On-board test indicator LED, and you can program to control it.
