KEHIPI 4PCS Pro Micro ATmega32U4 5V 16MHz Development Board
Pack of four ATmega32U4 boards with 5 V logic, 16 MHz clock, micro-USB programming and 12 digital I/Os
- ATmega32U4 at 5V 16MHz delivers responsive control
- Pre-flashed bootloader works with IDE v1.0.1 for quick starts
- Hardware Rx/Tx serial simplifies device communication
- 12 digital I/Os plus 10-bit ADC on 4 pins expands sensing options
- On-board Micro-USB connector enables direct programming without extra hardware
Four-board development pack
The KEHIPI 4PCS Pro Micro ATmega32U4 5V 16MHz Development Board set supplies four microcontroller boards for makers building USB-enabled projects. Each board ships with the bootloader installed and pin headers fitted, ready for immediate use in keyboards, controllers or sensor nodes.
IDE 1.0.1 and USB limits
Programming relies on the Arduino IDE from version 1.0.1 and the on-board Micro-USB connector, so a host computer with a compatible USB port is required. The hardware serial Rx and Tx pins provide a direct UART link, but the USB interface itself is limited to full-speed operation.
12 digital I/Os and 10-bit ADC
Each board exposes 12 digital I/O lines and 4 analog inputs with 10-bit resolution, giving enough pins for moderate switch matrices or sensor arrays. Projects needing more analog channels, higher-resolution conversion or additional PWM outputs will exceed the capabilities of the ATmega32U4.

Questions about this item
Should I choose the 4-board pack or a single board for my project?
The listing supplies four identical Pro Micro boards, each with an ATmega32U4 running at 5 V and 16 MHz, so one pack covers multiple prototypes or spares.
What does the 16 MHz clock speed mean when the board is running my sketch?
The ATmega32U4 executes instructions at 16 million cycles per second, giving deterministic timing for USB communication and real-time I/O tasks.
How does the Micro-USB connector limit programming and power options?
The on-board Micro-USB port handles both 5 V power input and serial programming through the pre-loaded bootloader, requiring only a standard cable.
