## Overview

The HiLetgo 3pcs ESP32 Mini Development Board is a compact, high-performance IoT platform featuring the ESP32-32 chipset with 520KB SRAM and 4MB flash memory. It supports dual WiFi and Bluetooth connectivity, powered via USB 5V, and offers 34 versatile I/O pins. Fully compatible with Arduino IDE, this triple-pack kit is perfect for professionals and makers aiming to accelerate their smart device projects.

## Description

Features: The chipset that incorporates is the ESP32-32 and a chipset for the CP2104 serial port with 4 megs of space for development. Power supply voltage (USB) 5V DC Micro USB connection; Compatible with Arduino Input/Output voltage 3.3V DC Operating current min. 500mA RAM 512kB I/O Pins 34 Package Including: 3* ESP32 mini ESP-32 Development Board

Review: Works With Homeassistant - Easy to program. Paired with sensors to create a wifi enabled endpoint. Easily programmed in homeassistant. Used a 3d printer to make a case for board and sensors. Used usb cable and old iphone 6 charger to power. Used presense and temperature sensor to automate lights.
Review: Want to get started with ESP8266 development? Start here! - These little modules run the Espressif ESP8285 chipset rather than the 8266, but this actually adds a bit more functionality but for most programming, you'd never know you were using the newer version. What makes these modules so great for prototype and developing on the 8266 platform is that it has a built-in usb connection and programming reset pin so you don't have to buy a separate cradle to burn ESP-01 modules. The boards are so cheap they work great as throw-away AP's if you need a 'mini router' to host other IoT projects, and the through-hole connections make using the GPIO pins a breeze. If you are programming using the Arduino IDE, you'll find that the standard 8266 examples (webserver, dns responder etc) will all work, and there are actually several wemos specific examples available as well. Great little board!

### ⭐⭐⭐⭐⭐ Seems to do the job!
*by P***A on August 29, 2023*

Got this little gem to work using the Arduino IDE within about 5 minutes of research. I grabbed the ESP32 Mini ESP-WROOM-32 Development Board. Don't be confused like I was reading the other reviews. I installed the esp32 v2.0.11 board package in the Arduino IDE and used the LOLIN D32 board that came with the board manager. Serial Monitor is working great along with a simple blink program. Here's a simple program you can run just to verify the LED blinks and outputs data to the serial connection. Overall, a solid 5 stars! #################################### #include <Arduino.h> const int ledPin = 2; // The onboard LED is usually on GPIO 2 int counter = 0; // Counter to keep track of LED blinks void setup() { pinMode(ledPin, OUTPUT); // Initialize the LED pin as an output Serial.begin(115200); // Initialize serial communication at 115200 baud } void loop() { counter++; // Increment the counter Serial.println(counter); // Print the counter value to the Serial monitor digitalWrite(ledPin, HIGH); // Turn the LED on delay(1000); // Wait for 1 second digitalWrite(ledPin, LOW); // Turn the LED off delay(1000); // Wait for 1 second }
