The boards are well manufactured. They are clean and the edges are smooth. Soldering is very easy. The AMS1117-3.3V does not fit, because Vin and Vout are exchanged. I wonder, if there is another voltage regulator for this board.
Needed it for Webradio project (Karadio). Very usefull. Nice feature: You can put a voltage regulator XC6206P332PR on it and remove the 0 Ohm resistance, like this it can be feeded by 5V.
Je les ai achetés pour souder des modules LORA les broches correspondent, j'aime vraiment que rien n'est venu monté ou soudé, donc je décide quoi souder et ce qui ne l'est pas. livraison très rapide, beaucoup plus rapide que aliexpress, 100% recommandé!
I used these for ESP8266 ESP-12F modules. Although I have not soldered SMD things yet, this operation was acceptable. :-)

Iterm received, solder with esp8266 module, program and working correctly!
regular pcb to solder modules
All right. Thank you.
I haven't used the product yet, but it was delivered exactly as described. Resistors populated, well-packed, promptly-delivered.
Good and useful for my home electronic projects
