Freenove Breakout Board for ESP32 / ESP32-S3 WROVER WROOM, Terminal Block Shield HAT with Pin Header, 5V 3.3V Power Outputs, GPIO Status LED

Lovely breakout board that's easy to use and works well. The value for money is good for prototyping as you save a lot of time vs soldering everything.

I do a lot of ESP32 development and have a very small workspace. This board allows me to see what each IO pin is doing with its LED lights and connect wire or plugs to each IO. The only grip I would have would be the bottom of the board with the protruding pins. They will scratch your work surface, So I placed rubber feet on the board. They should have included them with the kit. The power strip screws are very tiny, and it does come with a screwdriver, Don't lose it. Its a very good board for trouble shooting as well. Does provide two way power connection and offers 3v & 5v power strips to connect your sensors or other DIY boards. There is one catch using this dev board. You have to use their ESP32 or ESP8266 board (FREENOVE) Which isn't a bad thing. They make very good EPS32 boards and very easy to program using VS CODE or Arduino IDE software. The IO pins are very well printed on the bottom of the board and on stop. It even has mounting hold to imbed this board into your DIY projects. I wished I had this board 3 years ago. Very good quality and sturdy.

This is a sweet idea. I bought one of each of their three configurations. Each pin has an LED on it, and drivers, and jumpers for either ground or VCC. If you are writing code, it's good to see what ALL of your outputs are. Beginner, or Pro, I think you'll find this gizmo worth your investment.

This product is excellent for a PERMANENT setup for an ESP32 or ESP32 S3 board. I say permanent because external power is needed for the Red Line of pins, the 5V column. Any of the Ground Pins Column can be used in USB mode however. The 3.3V next to the Power Input can be used in USB mode, however there are only 8 pins for this usage. Pros: Each pin slot has a Female Hole for Male Pins for screwing it down to connect. Each pin has Male Connectors for Signal, 5V and Ground. There is also a set of 8 (Eight) male pins for both 3.3V and Ground. Cons: The column of Red Pins (5V) is only usable with an outside power source, 7-12V.

Extremely handy for viewing what your microcontrollers are up to, and connections are nice and easy. I like using these in small din-rail mounts for projects I expect to mess with every so often. Standard barrel jack makes for easy hookup, though it might be nice to support 12v instead of just 5v. Each side has a swappable rail between 3v3 and 5v, so powering accessories as well as your microcontrollers is nice and easy. As long as your board features legends on the top side it's super easy to wire with, and I've not had any boards in the two-row style not work with it so far. If you want flexibility and ease and don't mind using up some space and paying a little for it, this is certainly worth the money, especially compared to the other boards that are dedicated to single microcontrollers.

Like promised: good quality and fast delivery

This breakout board is a real joy to use. It provides an LED indicator on nearly every pin, and accepts an external power source. Those LEDs are handy when troubleshooting, and they saved me time identifying connection mistakes quickly. Keep in mind, the screws on those terminals are tiny, but the supplied screwdriver is adequate. Once paired with my ESP32-S3-DevKitC-1, the assembly still fits in the box supplied with the product, which is kind of a bonus. This product may not work with every ESP32 variant, so pay close attention to the pinouts of your development board and compare with those found on this breakout board. At first glance, I wasn't sure this would work with my ESP32-S3-DevKitC-1, but it works great. The breakout board has 40-pins, but the (DevKitC) ESP32-S3-WROOM-1 breakout has 44-pins. The 40-pin socket simply plugs in to the middle 40 pins of the DevKitC, with one pin unconnected at each end. This is not a problem, since those pins are redundant 3V3 and GND pins. Just for fun, enjoy this quick sample code to see all those LEDs in action: #include <Arduino.h> const int gpioPins[] = { 4, 5, 6, 7, 15, 16, 17, 18, 8, 3, 46, 9, 10, 11, 12, 13, 14, 2, 42, 41, 40, 39, 38, 37, 36, 35, 0, 45, 48, 47, 21, 20, 19}; const int numPins = sizeof(gpioPins) / sizeof(gpioPins[0]); void setup() { for (int i = 0; i < numPins; i++) { pinMode(gpioPins[i], OUTPUT); } } void loop() { for (int i = 0; i < numPins; i++) { digitalWrite(gpioPins[i], !digitalRead(gpioPins[i])); delay(100); } } update: I'm taking a few stars off. The 5V signal pin on the breakout isn't connected with the DevKit 5V pin. The product description clearly states the abundant (red) 5V0 pins on the breakout are only powered by the external power supply. But the ESP32-S3-DevKitC has a dedicated 5V pin from the 5V+ supplied by either USB port. FYI, the USB port powers the DevKit when no external supply is used. This pin is broken out in the lower-left corner to a blue LED. But, sadly, it is NOT connected to its adjacent (yellow) signal pin. Instead, the pin is tied to all the other (red) 5V pins powered by the external supply through the buck convertor. As far as I can tell, this is the ONLY (yellow) signal pin on the breakout not connected with the corresponding pin on the DevKit. The whole point of the breakout is to make connection with and troubleshooting of the smaller DevKit easier. I presume the designer of this breakout felt users may try to power external devices from the yellow 5V signal pin, and felt it necessary to block them from doing so.

Used these breakout boards to wire up some WLED controllers. They were considerably easier to use than the other esp32's I have been using where I had to solder leads to them. They are currently running multiple led light strings and have performed flawlessly. Do keep in mind that they only work with their brand of boards. They are pinned out differently than the other ESP32's I have used on on other projects.

C'est la troisième carte que j'achète, j'ai déjà celle pour le Pico W, l'esp32 (sans les connecteurs bus d'alimentation qui sont un réel plus) et je viens de commander celle pour le Raspberry pi 4. Attention, les borniers sont petits (en 2.54mm, heureusement, le petit tournevis est fournit avec). Je recommande vivement pour le développement et même plus....

I like these boards for development work. The terminals are clearly marked, which is great because the Pico's do not have pin designations on the top surface. Each pin has both a screw terminal and a male pin, making interconnection easy. They also have LED's which show the state of each pin.

Bellissimo e utilissimo accessorio Ben fatto, pratico e pieno di risorse ... pin a non finire, led che identificano attività sulle porte, un must. Attenzione al passo della scheda perchè non è compatibile con tutte, c'è scritta la dimensione, controllatela

great board. easy to see if a pin is active with a status LED on every pin.
