    The packaging was adequate to protect these boards during shipping. I uploaded a custom blink program to test these and they worked as expected. Now I have some 3.3v boards to add to my collection. There are not enough header pins for every socket. The 4 sockets in the center of the board don't get header pins, but since most usage doesn't require all pins it should be fine. This looks to be a very good clone, all the pins match with the real thing and it works perfectly. I had to mark the bottom to indicate the Frequency and Voltage after testing to verify voltage. It was not marked in the factory. I tested the voltage by applying 9v to the RAW pin and measuring voltage to ground on the VCC pin. It was exactly 3.3v. Overall a great addition to my collection and I should get around to using all of these eventually, lol.

    Come unmarked on the back of the PCB (3.3V / 5V, frequency) so you better mark them upon receipt if you don't want to lose time sorting them out of your pile of MCUs :-) No much else to tell about these modules, they're the usual Pro Minis and they don't do more, nor less, than other Pro Minis. I'm glad they come without the headers soldered, it makes it easier to integrated them with other modules.

    Works well. Hooked it up to an FTDI USB to Serial Converter for programming. Works smoothly with Arduino IDE.

    Item arrived in 10 days and was exactly as advertised.very easy to get going and use. I’m very happy with them. Amazon was charging over $11 for three of them. Banggood’s was half the price. That’s why I buy from this company, they have the best prices and 10 days delivery is fine with me I just plan accordingly. 👍
