ESP-WROOM-32

I finally made the switch from Arduino to ESP32 - what a difference! I was up and running very quickly since the Arduino IDE easily recognized this module. I'm just OK with coding but with the help of an online AI program, I was getting several projects running fast! Hook up is a breeze as all of the pins are identified by silk screened markings. The only downside to this is the pin spacing from one side to the other - it's too wide for my old prototyping breadboard (it's one row too wide to fit). Luckily, for my project shown, I only needed 4 pins that were all on the same side. I'm going to order a new breadboard to address this issue. The module is very well built and has two onboard LEDs and two buttons - one of which is a handy reboot. At around $5 per module, this is a GREAT deal!

Easy to set up and use. Fast and works well. Built well, also easy to connect with jumper wires or soldered on wires.

Good Product

It works great, but be warned that it is an odd form factor if you’re looking for CAD models online. I was trying to design a PCB for it and found it was a little tricky due to the pinout being inconsistent with similar models. Other than that, no complaints. I’m using a Bluetooth controller library and was able to connect it to an Xbox controller with no issue.

Wish they gave a cable along with it. Other than that works fine .

Great devices on the cheap and fast!

Only three of these worked. The other three aren't even detected when I plug them in. I'll be returning them.

Works as it should

This ESP32 board is a good board for programming and playing with different IOT devices. If you have extra boards and sensors, you can connect it with this board and do some Arduin programming to control them. This is a good board to start experimenting with it. I have other sensors also, so I am trying out different programs from online sources and controlling simple items like led lights.

All work as they should. A couple of solder joints are not that great. I was able to fix them. Good for the price.

The ESP-WROOM-32 dev board is incredibly versatile for IoT (Internet of Things) work. I’ve used it for everything from sensor monitoring to LED control, and it’s never let me down. The dual-core processor handles multitasking smoothly, and having both Wi-Fi and Bluetooth built in makes it great for connected devices. Flashing firmware through the Arduino IDE or ESPHome is straightforward once you install the drivers, and it works with both USB-C and micro-USB versions depending on the board you get. The onboard antenna has strong range, and GPIO labeling is clear. Excellent value for prototyping or permanent smart-home installs.

These just work. easy to program, come with pins pre soldered for easy wiring. I have been able to power small projects with only using the USB port for power. They seem to be protected well cause even with hot swapping, shorting out or reverse polarity they just reboot and keep on truckin.
