AZDelivery ESP32-DevKitC NodeMCU WiFi WLAN CP2102 ESP32-WROOM-32D IoT 2-In-1 Microcontroller Bluetooth Module Development Board compatible with Arduino including E-Book!

This is a veritable powerhouse of a microcontroller board, with both WiFi and Bluetooth, plenty of RAM and flash memory, digital, analogue pins (and touch inputs), together with hardware features like random number generation, hall effect sensor, etc. I can pretty much guarantee that no-one will actually use ALL of the capabilities. Running at an impressive 240 MHz, it is no slouch, but it can also go into a deep sleep when extremely long life on battery power is needed. The documentation on the manufacturer's site (Espressif) runs into thousands of pages (more than 800-page pdf hardware manual alone). Despite all this, it is as easy to get beginner level code running (blinking LEDs, etc.) in the Arduino environment as it is for its little brother, the 8266, or any other board such as the Arduino Uno or Nano. There is an error in the silk-screen printing on the board where a pin is labelled 'GND' where it should be 'CMD'. It is worth keeping away from this end of the board anyway as, apart from the 5V pin if needed, most of the IO pins are reserved for internal use to access the 4 megabyte flash memory. 3.3 volt power and ground are available at the other end of the board. If you need an accurate pinout, just look up 38-pin Devkit-C on the Internet. I keep a printed copy at hand as the print on the board is not only difficult to read, but nowhere near as informative as my printed crib sheet. For example, take the silk-screen pin IO22. My sheet tells me that is pin 39, GPIO22, PWM is available, it is also the SCL pin for the default hardware I2C bus and the RTS pin for the first serial port. I can also see that it is not one of the nine touch-sensitive pins. For breadboarding, I have joined together two boards, but have removed the power bus from one of them. This results in plenty of access to the ESP32 pins with the added bonus of a central 2 wire-bus (ideal for I2C) running underneath. See photo. Conclusion: I favour the 8266 in the guise of the D1 mini boards for most projects, but as soon as the project needs a bit extra, like more than one analogue input, or bluetooth, or just a bit of extra speed, that is when the ESP32 comes in. For just a small extra cost this solves the problem with little or no change to the source code. The only improvement I can think of would be a version akin to the D1 mini, where the surplus pins are removed and both sides of the board are used to result in a smaller module with no loss of facilities.

ESP32 - My Favourite Tinker Board Once again, AZ Delivery provided a high quality item and a competitive price and delivery to the UK was very quick. Just a couple of days. Some other reviewers seem to have had issues with the markings for the pins. Having checked the yellow legged version I recieved, everything is marked up perfectly. Meybe this issue has now been addressed? Having used various boards based on the Atmel chips and several Raspberry Pi variants, I was a little curious how this would perform and can honestly say, the ESP32 is now my favourite tinker board. It’s just so versatile. There is a lot that this thing can do – IoT, WiFi scanning, messaging…it can even play Doom! I’ve only started to scratch the surface of the available functionality but has so many possibilities. For a quick test I tried the Wifi scanned example. Loaded the board config into the Arduio IDE, uploaded and fired up the serial monitor. Straight away, I was seeing all the WiFI available in my area. To test connectivity with other devices, I set up a BMP280 and AZ-Devlivery SH1106 OLED screen on a breadboard and tweaked the Adafruit BMP280 sketch to output to the screen With a quick little sketch the results were fast and accurate. Now I can go on to expose these values over the web or post them in a message queue or allow queries over WiFi or Bluetooth. So much this little board can do! My only gripe is that it came pre soldered with a male header. The format of the board makes it too wide to fit on a single breadboard and with the pins exposed underneath, there is no indication what the layout is on the bottom of the board. My preference would have been for the header on the top of the ESP32 dev board. But that will be an easy change for me to make. Overall, I love this little board and look forward to exploring its capabilities. There is a lot of information, documentation, tutorials and support on the web for it, too.

I’ve used ESP8266/NodeMCU for a while, and ESP32 is a step up in power and functionality. This board from AZ-Delivery will take care of pretty much anything a maker/hobbyist can throw at it. It would even give a good account of itself in professional/industrial applications. Although newer than the ESP8266, support for ESP32 is growing, and it is easily integrated into the Arduino environment, with plenty of libraries and examples to get a user up and running quickly. Worth checking which pin the built-in LED is on, Pin 1, I think (usually Pin 2 on this type of board). Supported by the popular Blynk IoT platform, advanced WiFi/IoT projects are easily handled by this board. As well as a serious step up in performance, with a dual-core 32-bit processor and 4M Flash, a key addition to the ESP32 over the ESP8266 is Bluetooth, offering both Classic and LE versions. Examples in Arduino work first time, and there are great articles at Random Nerds Tutorials for the beginner. Took about 10 minutes to get values from a light level sensor streaming to a BT terminal on an Android phone. I love it when stuff just works! Once I’d seen how easy this board was to use in Arduino, I decided to try programming in Python, or rather the embedded version, MicroPython. This is where the extra Flash memory comes in useful. Again, there is good support for this board at micropython.org, and it works well with popular IDEs such as Thonny and uPyCraft. Once again, the guys at Random Nerds Tutorials have some great step-by-step articles to get you started.

Works amazingly !! So great for projects

Kanon ! Dom funkar kanon till Home Assistant som det är tänkt
