I received this product to replenish stock as I was using them for interfacing different devices to PC routinely. Initially I could not configure the received one as I did in the past with the ones I had. A closer look revealed that the chips marking differs. The markings on the package are done in different font, and ST logo and manufacturing information is removed with the laser. Counterfeit controllers were reported recently on eBay. The picture shows the chips in blue (top) and yellow (bottom) cases from a new purchase. Their electronic signature showed Device ID 0x410 Rev.x. The flash memory size on the top device is 64kBytes, and on the bottom device 128kBytes. Because of smaller memory size, the top device cannot be reprogrammed with few open source debugger probe firmware found on the web. Both devices can operate as "ST Link v.2.0" with STLinkV2.J34.S7.bin firmware tested. Beware!Read full review
