Fi and Bluetooth ready module. Introduction. While ESP8. Wi. Fi development board in handmade Io. T projects, the new ESP3. Although its not so new, the ESP3. Bluetooth capabilities, but not only. The ESP3. 2 comes now with almost 3. IO pins and a powerful 3. CPU ready to process more complex jobs. When I first got introduced to the world of the ESP8266, I had a real hard time to find a way to flash the firmware of the ESP826601 with an Arduino Uno. The ESP8266 WiFi Module is a self contained SOC with integrated TCPIP protocol stack that can give any microcontroller access to your WiFi network. The ES. Despite those new features, the ESP3. Getting started with ESP3. ESP3. 2 technical specifications. Same as ESP8. 26. ESP modules, ESP3. You can see below main specs for the most common versions Processors Main Tensilica Xtensa 3.

JPG' alt='Software Serial Esp8266 Pinout' title='Software Serial Esp8266 Pinout' />ESP3. Function Block Diagram. ESP3. 2 available modules and development boards. Over the internet ESP3. The standalone version has pretty much the same design as the ESP8. The difference between them is the ESP3. See below some pics with the standalone ESP3. ESP3. 2 Standalone module. ESP3. 2 development board by Sparkfun. As you have used so far, there is nothing that Spark. Fun doesnt do. They also sell a nice red ESP3. Despite there are still allot of features under development, their version seems to be very stable, and also offers a Li. Po power input. You can see all details in the images below Sparkfun ESP3. Crack Monkey Psa. Development board. Sparkfun ESP3. 2 Development board pinout. ESP3. 2 development board by Adafruit. On the other side, Adafruit does a better job with the WROOM 3. Their version look more classic, feels much solid, and has a similar design with the well known ESP8. Node. MCU Lua boards. Images talk below Adafruit ESP3. Development board. Adafruit ESP3. 2 Development Board WROOM3. Other ESP3. 2 development boards. Nevertheless the direct competitors are, off course, the cheapest too, the Chinese clones. The same way as with the Arduino UNO, clones or genuine, all have the same esp. Espressif Systems. So the difference is only in the quality of the electronic components and the soldering precision. After a quick research on the internet, the most common clones seems to be made after the genuine Adafruit ESP3. I have bought one of those BUY Now from Amazon and SAVE money, and I will share with you some details. Below you can see how it looks ESP3. DOIT Devkit V1 Development board. Interesting similarities with the Adafruit model no You could easily confuse them, but at a closer look, the Adafruit has some protection components, and a different layout. Both have CP2. 10. USB bridge, a microusb port, but different voltage regulators. Also they feature two push buttons, one for reset function, and one for changing the boot modes. You can also find a red version which has the CH3. USB UART Bridge, for those who have issues with CP2. WEMOS also manufacture a board which they call LOLIN3. BUY Now from Amazon and save money and integrates the ESP3. It looks slim but solid, and some people found a version which claim to have incorporated battery slot like in the image below We. Mos ESP3. 2 Development Board. ESP3. 2 Development boards with OLED display embedded are also very common over the internet. This boards are very appreciated by the students because they can be easily transformed into data loggers or Wi. Fi Access points stations, with live data display. Be aware that power consumption is higher on this devices. You can see bellow few of this models Makerfocus ESP3. OLED Development Board BUY now from Amazon SAVE MONEY ESP3.

ESP3. 2 Pin Layout and Electrical characteristics. IMPORTANT Before reading any technical information, you should first know that ESP3. As you can see below, there are 4 different ordering codes Ordering code. Core. Embedded flash. Connection. Package. ESP3. 2 D0. WDQ6. Dual core. No embedded flash. Wi Fi bgn BTBLE Dual Mode. QFN 66.

Pin layout can have slight variation between chip versions. Below image is extracted from Espressif datasheet and represents the QFN 6 code version ESP3. Chip pinout layout. ESP3. 2 power consumption. The power consumption of the ESP3. Same as his predecessors, ESP3. You can see in the table below all power modes and resources availability Power mode. Active.

Power consumption in active mode. The ESP3. 2 electrical absolute maximum ratings are very similar with ESP8. Ghz RF chip. Because this radio chips are working with a low range voltage, powering the entire module with a 5. V supply is not yet possible without a third party voltage regulator. In the image below you can see the exact numbers for which the ESP3. ESP3. 2 Maximum absolute ratings. ESP3. 2 Bluetooth capabilities. One of the most interesting feature of esp. Io. T module, is the Bluetooth.
