Doesn't fit standard 25.4mm ESP32 devkit boards
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).

    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

    1.0 out of 5 stars Wrong dimensions for associated ESP32 board
    Reviewed in the United Kingdom on 29 December 2024
    Verified Purchase
    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

    They're about a mm off so the sockets have to taper in to fit them. It's not terrible but it's not perfect. They still work

    Reviewed in the United Kingdom on 25 February 2024
    Verified Purchase
    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.

    Reviewed in the United Kingdom on 30 June 2023

    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.

    Reviewed in the United Kingdom on 28 March 2023
    Verified Purchase
    In general it does allow you to plug in an ESP32 and give you terminals to wire to. But the board legend doesn’t match that of the ESP32. The socket strips are also longer than that required for an ESP32.
