FTCBlock Mini Nano V3.0 ATmega328P Microcontroller Board with USB Cable for Arduino (2pcs Boards+2pcs Cables)

Couldn't program it until I looked up how to set up the Arduino IDE properly. You have to set (in "Tools"):Board: Arduino NanoProcessor: ATmega328P (Old Bootloader)Port: COMn: where n is usually 9 or above - it will pop up on the menu. Never COM1: (which is on the motherboard of your computer.)After trying to communicate a bunch of other settings, I found this in another Amazon review. If you still can't communicate after this, reboot your computer because Arduino IDE sometimes scrambles your COM port when connection is unsuccessful.It is a nice board and the price is right!

I struggled with it a few times because you didn't come with any documentation, but I played around with it and I figured out what it was an old bootloader version of the chip.It works great for what I need it for!

I initially thought this didn't have a bootloader but after much searching I found a fix. The solution for me was in IDE: Tools -> Processor -> ATmega328P (Old Bootloader). When I changed that setting I was able to program the nano as expected.

Product does not allow uploads. AD says some computer driver needed but What? No mention of what or how to get it? I'll keep looking but so far DOA. Well I found that it missing the ISP bootloader. Easy fix, google it to see how to easily add the boot loader. Once loaded unit functions well.

Chip has no bootloader. I have to purchase a known working Ardunio to copy the bootloader. If I have to do that I will just throw this in the garbage and use the real thing! I thought I was getting the real thing when I bought this but now I know. Don't waste your time with this junk.

Unlike the original this requires special Usb driver, was difficult to install. But works fine once installed

Works great!

Good board components a little bulky
