The Pro Micro is similar to the Pro mini except with a ATmega32U4 on board. The USB transceiver inside the 32U4 allows us to add USB connectivity on board and do away with bulky external USB interface 2. This tiny little board does all of the neat-o A-rduino tricks that you're familiar with: 4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V, this board will remind you a lot of your other favorite compatible boards but this little guy can go just about anywhere. If you're supplying unregulated power to the board, be sure to connect to the "RAW" pin on not VCC. 3. This latest revision corrects the silk error from the last version of the board so that pin 14 is correctly labeled. We've also added a PTC fuse and diode protection to the power circuit and corrected the RX and TX LED circuit. Feature: ATmega32U4 running at 5V/16MHz Supported under A-rduino IDE v1.0.1 Recommand power supply for board: 6-7V, less than 9V On-Board micro-USB connector for programming 4 x 10-bit ADC pins 12 x Digital I/Os (5 are PWM capable) Rx and Tx Hardware Serial Connections Our SmallestCompatible Board Yet Package includes: 3pcs Pro Micro ATmega32U4 Module Review: Great little board - Yes, this is a Leonardo, which IS a Pro-Micro, but with more pins. The fact that we can't downvote the reviews that are complaining about his is ridiculous. Board works great, flashes very fast. Only downside is the lack of documentation and pinouts, but if you search enough you can find them. Besides the screenprint on the board here is more pin info. Note that the pinouts on the board are NOT in order, so take notice. I'll go down the left side of the board. I'll list the board description along with features. When you see just a number, that's a digital IO TX0 - 1 (this is "digital pin 1") TX1 - 0 GND GND 2 - SDA - A4 3 - SCL - A5 - PWM 4 - A6 5 - PWM 6 - A7 - PWM 7 8 - A8 9 - A9 - PWM on the right side of the board, going down RAW GND RST VCC 21 - A3 20 - A2 19 - A1 18 - A0 15 - SCLK 14 - MISO 16 - MOSI 10 - A10 - PWM Review: Cable Issues - These worked just fine after some cable trial and error. Not all USB cables are created equally so if your new card doesn't respond when plugged it, try a different cable (preferably one that came with a phone). Once recognized by my PC everything worked as it should! ## Features - ATMega 32U4 AU running at 5V/16MHz,supported under IDE v1.0.1 - On Board micro USB connector for programming - 4 x 10 bit ADC pins - 12 x Digital I/Os (5 are PWM capable) - Rx and Tx Hardware Serial Connections ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08THVMQ46 | | Brand | Teyleten Robot | | Built-In Media | 3 x Pro Micro ATmega32U4 Modules for A-rduino | | CPU speed | 16 MHz | | Compatible Devices | Devices supporting A-rduino or Arduino communication protocols | | Connectivity Technology | USB | | Connectivity technology | USB | | Customer Reviews | 4.2 out of 5 stars 129 Reviews | | Included components | 3 x Pro Micro ATmega32U4 Modules for A-rduino | | Item Dimensions L x W x H | 33L x 15H millimeters | | Manufacturer | Teyleten Robot | | Mfr Part Number | F25 | | Model Name | Pro Micro | | Model Number | F25 | | Model name | Pro Micro | | Operating System | Linux | | Operating system | Linux | | Processor Brand | Microchip Technology | | Processor Count | 1 | | Processor Speed | 16 MHz | | RAM Memory Technology | LPDDR2 | | Total Usb Ports | 1 | | Unit Count | 3.0 Count | | Wireless Compability | Bluetooth | ## Product Details - **Brand:** Teyleten Robot - **CPU speed:** 16 MHz - **Connectivity technology:** USB - **Included components:** 3 x Pro Micro ATmega32U4 Modules for A-rduino - **Model name:** Pro Micro ## Images ![3pcs Pro Micro Atmega32U4 5V 16MHz Bootloadered IDE Micro USB Pro Micro Development Board Microcontroller Compatible to Arduino Pro Micro Serial Connection with Pin Header - Image 1](https://m.media-amazon.com/images/I/61QY+vZBNJL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great little board *by B***. on 14 November 2025* Yes, this is a Leonardo, which IS a Pro-Micro, but with more pins.

Not all USB cables are created equally so if your new card doesn't respond when plugged it, try a different cable (preferably one that came with a phone). Once recognized by my PC everything worked as it should! ### ⭐⭐⭐⭐⭐ Best All Around *by A***R on 31 January 2026* It is my go to for most things I need. It compiles and loads fast. I use it to automate mouse and keyboard tasks. It is the first thing I grab to test peripherals because it seems faster to use. I bought this after trying the USB-C version (because I'm used to the micro USB and expect the USB-C to replace it eventually). ADC behaves differently but did not spend time to understand the difference; it was a problem for something I was trying. The USB-C is harder to insert and remove. So I bought three orders of this in case the micro USB is no longer available. ## Frequently Bought Together - Teyleten Robot Pro Micro Atmega32U4 5V 16MHz Module Board Micro USB Pro Micro Development Board Microcontroller 3pcs - Teyleten Robot Dual-axis XY Joystick Module PS2 Game Joystick Control Lever Sensor Game Controller Sensor Board Module KY-023 for Arduino Raspberry (5pcs) - IWISS 1550PCS 2.54mm Pitch Wire-to-Wire Dupont Connector Kit, Includes Pin Headers, Jumper Wire, Crimp Pins for RC Servo, Arduino, SMT, SATA, EPS, PCIE, Battery Balancer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/330119437-3pcs-pro-micro-atmega32u4-5v-16mhz-bootloadered-ide-micro-usb](https://www.desertcart.jp/products/330119437-3pcs-pro-micro-atmega32u4-5v-16mhz-bootloadered-ide-micro-usb) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-13*
