2 Pcs ESP32 Breakout Board ESP32 Expansion Board 38Pin Development Board with Wireless WiFi Bluetooth for ESP-WROOM-32 Microcontroller Development Board

These dimensions might be 0.3mm on the large size as im printing a housing to go around the terminals to make sure they never rotate (as I typically break them by tighting the terminals a bit too much) and to help mounting and vibration Oh and im soldering a gyro and acc to it

Got these as the breadboard on my current project was getting really messy. Don't think they'd last too long with repeated use as a prototyping board but as a permanent solution they're fine. Headers for the ESP32 are solid and line up perfectly and terminal blocks are okay. No problems with shorts or dodgy connections. I'm using 1.5mm multicore wire on some of the connections which is a snug fit but that's overkill on my part. All in all, very pleased for the money.

In common with many other reviews, this board is wrongly sized for the associated ESP32 boards. Why does Amazon allow this issue to continue??? I have purchased this product on two occasions. First, in October 2024 the board was printed 0616. This board is fiune with all my ESP32 and lateral pitch between DIL rows is 25.8mm Sadly, although these boards appear to be electrically OK, they are warped. The second occasion produced boards printed "FOR ESP32 TERMINAL ADAPTOR" and having a pitch between rows of 23.7mm. These boards do not fit either of my ESP32 types, and certainly not the ESP32 boards with which they are linked, and sold. So - it seems there are two distinct types of boards, and those currently available are unsuitable. Really time that Amazon recognized thgis as a generic issue and did their own QC check

The pin spacing was a bit off but with a bend of the socket it fitted all be it tight

Not sure why some reviews talk about pin spacing issues as my ESP32-WROOM-32D devices fit perfectly. Really good for wiring up the ESP32 in production mode with external power supplies for example and being able to unplug the ESP32 for re-programming without interfering with external power supplies, or to enable easy replacement in the field should the device fail in the future. Picture shows a prototype device with ESP32 driving 8 mains solid state relays with six DS18B20 bus oriented (single data wire) temperature sensor inputs and it all works brilliantly.

Well made, useful breakout

Firs and works as it should

In common with others, I found these boards to be incorrectly sized for use with 25.4mm ESP32 devkit boards. While the description of the product says it is suitable for "narrower width" boards, I think the opposite is true: this probably fits wider 27.9mm boards correctly, but I do not have any to check. I tried it with both an Espressif ESP32-C6-DevKitC-1 board (pictured) and a third-party ESP32 board, both 25.4mm wide. In both cases, the sockets were a few mm wider than the headers on the board, meaning only one header could be inserted (unless you're prepared to bend the pins).

Envío rápido y comunicación del vendedor por cualquier incidencia. Las placas de muy buen calidad. Los terminales están perfectamente alineados, no entiendo algunos comentarios. En mi caso las utilizo con un ESP 32 WROOM-32 de AzDelivery comprados en Amazon. Lo digo por si alguien tiene problema de pines. 38. Encajan a la perfección. Resumiendo muy satisfecho con la compra.

Die Adapter wurden schnell geliefert. Sie passen genau für die ESP32 WROOM von AZ-Delivery. Soll heißen, der Abstand der Sockel ist wie in der Beschreibung angegeben genau 25,5mm. Die Lötpunkte sind sauber ausgeführt, von daher sollte es keine Probleme geben. Wir können die Schraubklemmenadapter absolut empfehlen.

Fungerar perfekt. !

Per gli esp 32 comprati insieme, sono perfetti

Très bon matériel
