I watched a YouTube video that only showed connecting VCC, GND, RXI, TXO. I discovered that the DTR pin must be connected in order to program the device properly. Unit is working great now. Review: Nice inexpensive Arduino boards for a specific project. - It was nice these came in a 3 pack. I need 3 for a specific Arduino project and these were perfect. I did not experience any issues at all using these boards. ## Features - Main chip: Atmel Atmega328P-AU - Fully compatible to Arduino Boards - Support Serial Download, 5V/16M - Support external power supply 3.8-12V DC - 3 Pin headers included ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07X2JGS69 | | Best Sellers Rank | #590 in Single Board Computers (Computers & Accessories) | | Brand | HiLetgo | | Customer Reviews | 4.3 4.3 out of 5 stars (117) | | Date First Available | August 26, 2019 | | Item Weight | 0.317 ounces | | Item model number | 3-01-1462-5V | | Manufacturer | HiLetgo | | Number of Processors | 1 | | Operating System | Linux | | Package Dimensions | 3.94 x 2.52 x 1.18 inches | | Processor | 16 MHz | | Processor Brand | Atmel | | RAM | SRAM | | Series | Pro Mini | ## Product Details - **Brand:** HiLetgo - **CPU Speed:** 16 MHz - **Connectivity Technology:** USB, Serial - **Memory Storage Capacity:** 16 MB - **Model Name:** Pro Mini ## Images ![HiLetgo 3pcs Pro Mini Atmega328P 5V/16M Replace ATmega128 Pro mini Atmega328 328P DC5V 16M for Arduino - Image 1](https://m.media-amazon.com/images/I/61+Fi3Nzx5L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Unit works fine. *by J***E on August 8, 2024* My first attempt to use this device did not yield a good result. I watched a YouTube video that only showed connecting VCC, GND, RXI, TXO. I discovered that the DTR pin must be connected in order to program the device properly. Unit is working great now. ### ⭐⭐⭐⭐⭐ Nice inexpensive Arduino boards for a specific project. *by T***A on November 21, 2023* It was nice these came in a 3 pack. I need 3 for a specific Arduino project and these were perfect. I did not experience any issues at all using these boards. ### ⭐⭐⭐⭐⭐ came with bootloader installed *by J***I on May 29, 2022* These arduino pro minis work perfectly, came with pre-installed bootloader, so no issues there. I’m not sure why others reported differently. My code uploaded and ran perfectly first time.
