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.

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.

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

These arrived in order. I still did not have a chance to test them but I need to write something down if I want to submit pictures of other product that arrived damaged in the same bulk/order. The Banggood should allow us to place just one review of the product we want and not force us to "all or nothing option" when it comes to writing reviews of the products form our orders. This means, for instance, if I ordered 100 products and if I want to write a review of just one product, I can't. I have to write review for all 100 products if I want to submit a review for a specific one. This is really bad solution. If there is a way to submit review just for one product from the order, please let me know.
