    It is the best board that you can get for your IoT projects. Workes flawlessly but you must know how to code and upload stuff in it before you buy this. I’m fully satisfies. I’ve been using this now for around 3 months, dropped it many times but still working fine.

    Node MCU was over all good but one pin was slightly bent, not a factor and also got a discount on the item. Packaging was good received through Delhivery.
