Difficile à souder correctement

Really good idea as at my age I can never remember pinouts. However to start with none of them worked which I thought a bit strange.I had already checked continuity on a couple of pins to ensure I put the ESP-01 in the correct position.It sticks out away from the adapter so as not to obscure the pin markings. There is an arrow on the board which points the direction the board should go.Further investigation revealed there was no connection between the ground header socket and the ground pin.Whether the through hole solder was bad or maybe even no track (difficult to follow).Simple solution was to solder a wire from the header to the ground pin, not a problem as the soldering iron was out to solder the 8 pins anyway.I would still buy again as they make wiring up the breadboard so much quicker.

Like other reviewers - ground pin not connected.Also, some only came with only one 4 pin header.

Les trous sont remplis d'étain ce qui rends la soudure des headers/broches très compliquée !!!!Je ne recommande pas sauf si vous voulez perdre 3x plus de temps pour l'assemblage.Par-contre les liaisons sont bonnes sauf sur un pcb qui n'avait pas de liaison tx.

I spent an entire evening wondering why I could not get this board to work. It looked like no power was getting to the ESP 8266. What a surprise, when I discovered this was actually true and it was because there is no connection between the ground pin on the chip and the ground pin on the board. You can make a modification to the board (see photo) to get this working but, frankly, I’d rather buy one that worked in the first place. Note that the same fault existed on all the boards in the package.
