This product suffers of several problems. (1) CH340 is supply with 5V so RX and TX are in 5V logic, but ESP8266 is not (officially) 5V tolerant. There is no level shift for 3.3V compatibility. I desolder Vcc pin of CH340 and connect it the output of regulator. (Note : There is no marking the CH340G chip : defective part ? ) (2) It's not a programmer at all. As stated in description, program button is not supplied. But there is no connector / no PCB track to put one. You need by yourself add it by soldering on the 2x4 header connector. Two buttons are recommended : one for GPIO0, and one for Reset. (3) The 1000µF is not connected to 5V but to 3.3V at LDO regulator output.

Китаец отправлял мой заказ полтора месяца!! На сообщения не отвечает! Из пяти заказанных товаров прислал четыре, модуль реле не положил. Спасибо Али, вернули деньги по спору. Не серьезный продаван не рекомендую.
