Dedicated to the Arduino Pro Mini board and other compatible board
More convenient to connect the peripheral module to Pro Mini board
Compatible with the pin definitions Arduino UNO R3
Use multi-color female header so that the interface is easy to identify and particularly noticeable.
Onboard 500mA resettable fuse to protect power supply from the USB port and the DC jack at the same time.
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.
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.
