## Overview

The HiLetgo Pro Mini ATmega328P 3.3V 8MHz module is a compact, low-voltage microcontroller board preloaded with a bootloader for immediate programming. Featuring 14 digital and 8 analog I/O ports, it supports seamless integration with popular 3.3V sensors and modules. Its small form factor and auto-reset capability make it an ideal choice for efficient, space-conscious embedded projects.

## Description

Specifications: Main Chip: Atmega328P-AU. The bootloader is already installed in the board. Flash Memory: 32 KB of which 2 KB used by bootloader. 8MHz clock frequency. USB connection off board. Supports auto-reset. Max 150mA output. Over current protected. Support external power supply 3.3V. Size: 33mm*18mm*6mm. 14 digital input / output port: RX, TX, D2 ~ D13. 8 analog input ports: A0 ~ A7. 1 pair TTL level serial transceiver port: RX / TX. 6 PWM ports: D3, D5, D6, D9, D10, D11. Note: *** Pro mini modules have a lower max current draw than the bigger UNOs and MEGAs, so do not run too many things off of VCC. Package included: 3* HiLetgo Pro Mini ATMEGA328P 3.3V 8MHz Module

Review: Reasonable prices - Always get what pay for. Good products, good price, good availability.
Review: Bootloader doesn't - I have purchased other HiLetgo products and they have always worked well for me. So, unfortunately I did not read the reviews. In this case I was looking to buy a Arduino Pro Mini compatible board. The HiLetgo part advertised that it came with the bootloader installed, so, I should have been able to program it just like the other Pro Minis I have been using for my development. No such luck. I tried both the Arduino IDE and Sloeber Eclipse. Having spent over an hour trying to get these to work, I'm sending them back. While I see that others have been able to get them to eventually work, these devices do not function as advertised. Although they seem a great value, if I can buy a plug & play device, then the time saved is more valuable.

## Features

- Pro Mini Atmega328 3.3V 8Mhz
- It has been programmed for its bootloader, without the user to buy ISP burner for programming, user-friendly.
- This board connects directly to the FTDI Basic Breakout board and supports auto-reset.
- Low-voltage board needs no interfacing circuitry to popular 3.3V devices and modules (GPS, accelerometers, sensors, etc)

### ⭐⭐⭐⭐⭐ Real workhorse
*by J***A on May 30, 2021*

Liked - works reliably, takes a lot of abuse and still keeps on ticking Dislikes - Not an issue with this specific supplier, but across multiple suppliers the header for the serial link is not consistent. Some suppliers the ground pins are on the right and other suppliers the ground pins are on the left side.
