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

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).

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.

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.

Even though the schematic for this board supports the hardware needed to support auto programming this board doesn't support it and comes with instructions on the anti static bag on how to program.There is a fix for this. If you add a small capacitor between EN and GND auto program will start working again. Its a fairly common issue with boards of this design, its a shame manufactures of these boards have yet to fix this issue.Other than that its a fine inexpensive breakout board / dev kit for the ESP32 WROOM

Bought this to start tinker with and for the value it is excellentEasy to setup and works with Arduino IDE, or VSC ode with the Platform IO extensionOne 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.

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

Simply didn't work, and quick touch of the board revealing some incandescently warm components around the power-deliver circuitry. Thermal camera revealed that something was bust there. Unfortunate, but these things happen. Seller was good and refunded immediately. It's possible this was an isolated incident and the next one will be fine, but I didn't bother.

Great item
