Product Description

NodeMCU is an open source IoT platform. ESP32 is a series of low cost, low power system-on-chip (SoC) microcontrollers with integrated Wi-Fi & dual-mode Bluetooth.

Our AZDelivery ESP32 Dev Kit C V4 corresponds 100% to the manufacturer Espressif, employs a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, with a clock rate of up to 240 MHz.

ESP32 is highly integrated with built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules.

It integrates a radio for WLAN (802.11b/g/n) and Bluetooth (Classic and LE). With the new board layout, both the power supply and the reset circuit for automatic programming have been significantly improved.

The WROOM module has been repositioned by Espressif to achieve a significant increase in transmission and reception quality without increasing performance. The WLAN function supports all common encryption methods such as WPA2.

It can also act as an access point or sniffer in the WLAN. There are more than 32 GPIO pins available, including UART, I2C, SPI, DAC, ADC (12 Bit), all GPIO pins can be used as input or output.

Features:

✔️ Able to achieve ultra-low power consumption.

✔️ Built-in ESP-WROOM-32 chip.

✔️ Breadboard Friendly module.

✔️ Light Weight and small size.

✔️ On-chip Hall and temperature sensor

✔️ Uses wireless protocol 802.11b/g/n.

✔️ Built-in wireless

✔️ Built-in wireless connectivity capabilities.

✔️ Built-in PCB antenna on the ESP32-WROOM-32

✔️ Capable of PWM, I2C, SPI, UART, 1-wire, 1 analog pin.

Pleasantly Surprised!

Size Name: ESP32 with CP2102Number Of Items: 3Verified Purchase
I bought these as I was undertaking a project for my home automation set up. They seemed particularly good value, especially as I got them using Prime. The delivery was next day, and the price for the three of them was around 21 quid - about the same as I could find on AliExpress.

They arrived well-packaged in a cardboard box, and each one was sealed in it's own anti-static bag and set in a small block of foam to protect the pins.

I use Home Assistant on a Raspberry Pi 4, and I flashed these using the ESPHome integration within Home Assistant. Instead of plugging these directly into the R/Pi, I plugged them into my workstation PC as the R/Pi is not really very accessible - although it works a treat over the network.

All went seamlessly.. and was straightforward using the ESPHome web UI. One small problem which I encountered was initially trying to connect to the ESP32 device via my USB port - when trying to connect via the ESPHome web UI, it kept bring up an error message saying "failed to open serial port" - this is not the serial port on your PC, but the serial port on the ESP32 board.. I overcame this by holding down the small 'boot' button, whilst clicking the 'connect' icon on the ESPHome web UI.. and it then connected, and I was able to install my yaml files. After this, I could then easily undertake Over The Air updates via the WiFi network without issue. I hope this helps somebody. 👍🏻

Would I buy them again??? Yes, without doubt. A good value item, that can provide endless fun if you are a fettler!

EDIT: I did buy them again!! Got another three to use so I can place some custom sensors and controllers around the house. I'll be using one to control my Rayburn Range cooker, both via a web interface and a Nextion screen which will be wall attached next to the cooker. Another will be used as a replacement boiler controller using digital temperature sensors to replace the old (and failing) electro-mechanical ones. This offers so much more flexibility for programming and efficiency of running - again, this will be web-enabled so I can get the data through via Home Assistant using my phone.

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.

Feature packed, powerful board, a few quirks
Reviewed in the United Kingdom on 16 October 2020
Size Name: ESP32 with CP2102Number Of Items: 1Verified Purchase
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.
