ESP32 WIFI+BLUETOOTH DEV. BOARD

<p><span style=”font-family:Arial,Helvetica,sans-serif;”><span style=”font-size:18px;”><strong>Description</strong></span></span></p>

<p><span style=”font-family:Arial,Helvetica,sans-serif;”><span style=”font-size:14px;”>This is the ESP32 DEVKIT DOIT board. There are two versions of this board, with 30 and with 36 GPIOs. Both work in a similar way. I prefer the version with 30 GPIOs because it comes with two GND pins (however, it&rsquo;s been difficult to find the version with 30 GPIOs available online). Also, even though the other model comes with more GPIOs, the extra ones are not recommended to use (they are connected to the ESP32 integrated flash memory).</span></span></p>

<p><span style=”font-family:Arial,Helvetica,sans-serif;”><span style=”font-size:14px;”>The pins are labeled at the top of the board, so it is easy to identify the pins to connect peripherals. It comes with on-board RESET (EN) and BOOT buttons. Additionally, it comes with USB-to-UART interface, so that you can easily program it using Arduino IDE or other development environments, and comes with voltage regulator circuit. The board can be powered using the micro-USB connector, or the VIN or 3.3V pins and it doesn&rsquo;t come with battery connector.</span></span></p>
