Review on 📡 REYAX RYLR896 Lora Module SX1276 UART 868MHz 915MHz Antenna Command FCC NCC by David Tison

3 received, one was a replacement for a broken chip. Replaced with a known working circuit. Advise me to do this to avoid a whole lot of mental anguish. Chip 1 worked fine, chip 2 didn't work, chip 3 broke the antenna. - I think the packaging. The soldered antenna on chip 3 now works fine, was very loose and rotated freely. Chip 2, the resistor under the antenna is a very bad connection. Molten and now works according to the same scheme as before. Revain will kindly replace it, but it's not needed at the moment. Keep an eye on the packaging if you are traveling alone. I think the flimsy envelopes are not good enough, if it arrives in a box with other things it should be fine. - The only thing I can think of is the difference.
