JZK ESP-32S ESP32 Development Board 2.4GHz WiFi + Bluetooth Dual Mode Antenna Module with Ultra Low Power

This ESP32 dev board is a gem! I needed its Bluetooth functionality, and it worked like a charm. Unlike other suppliers, there’s no need to fuss with the reset button – it’s super smooth to use. Other features like WiFi, fast processor, and large flash make this the ultimate Arduino replacement. Plus, it’s budget-friendly, and perfect use with your IOT projects. It’s easy to connect sensors, and phones to communicate with other devices. Honestly, I can’t see any negatives. For tinkerers enthusiasts, this ESP32 board is a winner. It’s great for many projects due to it's diverse features. Also, the Arduino plays well with the IDE, allowing for faster development.

Disclaimer - I received a full refund after reporting a minor fault, making my unit effectively free. This is probably the lowest one-off price you'll pay for an ESP32. EPS32s a great. Highly recommended. It's a fully functional and easy to use Bluetooth/WiFi module with a micro-controller built in; or a micro-controller with a WiFi module built in - whatever way you want to look at it. Forget Arduinos and shields, this is everything in a tiny package. The hardware is open source (credit: Wei Wang/doit.am), so there are many variations to choose from. This PCB version is 0.1" wider than some ESP32 modules (see photo), which leaves rooms for mounting holes but with molex pins attached it's a row too wide for a standard prototyping board. Mine arrived with a fault in the molex pins, which were soldered on at a funny angle. I got a full refund without even asking for one so I can't fault the customer service. I'm assuming mine just slipped through quality control, but as I will probably remove the pins anyway (a complete pain to do) so I can attach wires to the PTH I could have lived with it. So in spite of the slight flaw, the customer service has restored it to five star. The extra width allows the edge pins to be silk-screened with labels, which is useful. Many of the pins are GPIO, and I believe there are three ACIAs (UARTS) built in; one of which is used by the USB via a converter chip. The whole thing runs beautifully cool. For software, the Arduino IDE "just works" with it, once you've installed the board package. And this includes complex libraries allowing you WiFi, DNS and IP socket drivers - including encryption on the WiFi and SSL. I absolutely love these boards. The picture is this board (right) next to a different, narrower, ESP32 board on the left. Both use the same ESP32 model at the centre. It shows the prototyping board problem, which is easy enough to overcome with a different prototyping board (or two of them).

Works well, just remember it's the "old" USB connector (not USB-C) and you'll need to use a wider breadboard, or two side by side. USB takes care of the reboot on code deployment, so you don't often have to hit the "boot" or "EN" buttons. can't find schema to control the red "always on" LED, however there's a small blue onboard LED which maps to GPIO-2. Never used these boards before but had it up and running, controlling LED, LCD panel and interfaced to home wifi within a couple of hours.

First impression: well made board. It has the older micro-USB connector for which I had to dig through my old cables box to find a suitable data-capable one. I am deducting a star because the usb type is not mentioned anywhere in the description. The board is too wide to fit normally on standard breadboards. However it conveniently has 3V3, GND, both I2C data and clock as well as a bunch of GPIO all on one side, which means that only one side of the board has to be plugged on the breadboard (see attached image for a small breadboard where I prototyped an air quality monitor with an I2C SCD40 sensor, an OLED screen and a push button). Despite what is mentioned on other reviews I flashed my code straight from the Arduino IDE (after installing the ESP32 Dev Module library) with no need to old any buttons on the board during flashing. Could I have received a new revision? Overall, a good quality, (not so) little board for the money. Just make sure you have a micro usb cable at hand!

Bought this to start tinker with and for the value it is excellent Easy to setup and works with Arduino IDE, or VSC ode with the Platform IO extension One thing to watch is to ensure your USB cable is a data cable and not just a charging cable. Ideal for anyone who wants to get into creating little electronic projects.

Below are tips for those new to the ESP32 to help you get going quickly with this superb little board. Please use a good quality usb cable it does make a difference to the 5v rail when usb powered. EN=reset, Boot is used to reliably upload your sketch, press and hold as soon as the IDE says Connecting....., only let go when you see upload activity. Be aware some pins are not available when using wifi, there are several board versions 30 or 36 pin differing slightly. Do not connect GPIO pins directly to Gnd use a 100 ohm resistor. Check out random nerd tutorials for further tips. Have fun regards Paul

Great little board, same its not usb c but runs WLED fine for controlling led strips

Detta är ett måste om man kör home assistant

Super für mein Bastelprojekt. Kleiner PC mit WLAN.

OK

ho ripetuto l'acquisto per la seconda volta. Sono a quota 4 pezzi e tutti funzionano , non posso dire altrettanto della concorrenza la stessa cosa che mi ha rifilato il 30% di non funzionanti su due acquisti.
