How to use?

1. Connected to the computer. (If the module is not recognized by your computer, please install the driver first)

2. Open IDE and load the blink skit.

3. Set the board to Leonardo and select the appropriate COM port (it has already been identified as Leonardo in the list).

4. One LED connected to pin 9 and modified the sketch accordingly.

5. Press upload and have flashing LED within a few seconds.

Note:

When you open the IDE software, please go to the tool and select the board \"Leonardo\" or \"Genuino Micro\".

Package includes:

4 x Pro Micro with ATmega32U4 chip 5 V 16 MHz module

• Maximum performance: the Pro micro microcontroller development board runs at 5 V/16 MHz and supported by IDE V1.0.1 for smooth programming. Suitable for Arduino.
• The NRF52840 chip uses an ARM Cortex-M4F processor, clocked at 64MHz, with built-in 1MB of flash memory and 256KB of RAM
• The NRF5280 development board has a 3.7V lithium battery interface and a software switch that can cut off the power of the LED. When turned off, the standby power consumption can reach 1mA
• SuperMini NRF52840 is a Pro Micro alternative development board that is compatible with Nice! for Nano. Its pins are the same as ProMicro, which means it can be used with almost any Pro Micro keyboard.
• Pro Micro with Atmega32U4 chip Development Board,Pro Micro 5V/16MHz Nano microcontroller Development Board with Built-in USB updater Type-C Interface Compatible with Arduino IDE
