The board has brought out most I/O ports to pin headers of 2.54mm pitch. These provide an easy way of connecting peripherals according to your own needs. When it comes to developing and debugging with the development board, the both side standard pin headers can make your operation more simple and handy. The ESP-WROOM-32 module is the industry's leading integrated WiFi + Bluetooth solution with less than 10 external components. It integrates antenna switch, RF balun, power amplifiers, low noise amplifiers, filters and power management modules. At the same time, it also integrates with TSMC's low-power 40nm technology, so that power performance and RF performance are safe and reliable, easy to expand to a variety of applications.</p><h2 data-id="technical-details%3A">Technical Details:</h2><ul><li>Microcontroller: ESP-WROOM-32 module </li><li>USB to Serial Port Chip: CP2102-GMR</li><li>Operating Voltage: DC 5V</li><li>Operating Current: 80mA (average)</li><li>Current Supply: 500mA (Minimum)</li><li>Operating Temperature Range: -40℃ ~ +85℃ </li><li>WiFi mode: Station/SoftAP/SoftAP+Station/P2P</li><li>WiFi protocol: 802.11 b/g/n/e/i (802.11n, speed up to 150 Mbps</li><li>WiFi frequency range: 2.4 GHz ~ 2.5 GHz</li><li>Bluetooth protocol: conform to Bluetooth v4.2 BR/EDR and BLE standards</li><li>Dimensions: 55mm*26mm*13mm</li><li>Weight: 9.3g</li></ul><h2 data-id="element-and-interfaces%3A">Element and Interfaces:</h2><p>Here is an explanation of what every element and interface of the board has:</p><div class="embedExternal embedImage display-large float-none"> <div class="embedExternal-content"> <a class="embedImage-link" href="https://us.v-cdn.net/6031942/uploads/SF436SK1ZJEC/image.png" rel="nofollow noreferrer noopener ugc" target="_blank"> <img class="embedImage-img" src="https://us.v-cdn.net/6031942/uploads/SF436SK1ZJEC/image.png" alt="image.png" height="1182" width="1038" loading="lazy" data-display-size="large" data-float="none"></img></a> </div> </div> <h2 data-id="specialized-functions-of-some-pins%3A"><strong>Specialized Functions of Some Pins:</strong></h2><div class="embedExternal embedImage display-large float-none"> <div class="embedExternal-content"> <a class="embedImage-link" href="https://us.v-cdn.net/6031942/uploads/NROJO6ZQCF1K/image.png" rel="nofollow noreferrer noopener ugc" target="_blank"> <img class="embedImage-img" src="https://us.v-cdn.net/6031942/uploads/NROJO6ZQCF1K/image.png" alt="image.png" height="825" width="417" loading="lazy" data-display-size="large" data-float="none"></img></a> </div> </div> <div class="embedExternal embedImage display-large float-none"> <div class="embedExternal-content"> <a class="embedImage-link" href="https://us.v-cdn.net/6031942/uploads/QBHYWJS55LYB/image.png" rel="nofollow noreferrer noopener ugc" target="_blank"> <img class="embedImage-img" src="https://us.v-cdn.net/6031942/uploads/QBHYWJS55LYB/image.png" alt="image.png" height="565" width="417" loading="lazy" data-display-size="large" data-float="none"></img></a> </div> </div> <h2 data-id="detailed-using-method-as-follows%3A">Detailed Using Method as follows:</h2><h3 data-id="step-1-install-the-arduino-ide">Step 1 | Install the Arduino IDE</h3><p>When programming the control board, first you should install the Arduino software and driver. </p><p>You can download the different versions for different systems from the link below: </p><p><a href="https://www.arduino.cc/en/Main/OldSoftwareReleases#1.5.x" rel="nofollow noreferrer ugc">https://www.arduino.cc/en/Main/OldSoftwareReleases#1.5.x</a></p><p><br></p><p>This control board is compatible with the Arduino 1.8.7 or latest version. </p><p>So next we will download the Arduino 1.8.7 software to test the keyestudio ESP32 core board.</p><div class="embedExternal embedImage display-large float-none"> <div class="embedExternal-content"> <a class="embedImage-link" href="https://us.v-cdn.net/6031942/uploads/KADR1AB7SVXA/image.png" rel="nofollow noreferrer noopener ugc" target="_blank"> <img class="embedImage-img" src="https://us.v-cdn.net/6031942/uploads/KADR1AB7SVXA/image.png" alt="image.png" height="622" width="1037" loading="lazy" data-display-size="large" data-float="none"></img></a> </div> </div> <p>In this Windows system page, there are two options.
