Terrible. Computer and accessories

One of the two is broken, see photo, there is a solder joint in the connection - ? if previously used. The 2nd does not work, looks like a solder joint touching another, compare 2, this connection is not in the broken one. waste of money and effort. I hope Revain intervenes, but I'm waiting for an answer. There are no messages from the seller yet. I will update if that changes.

This device is not suitable for use in North America

SX1278 radio module frequency is 433MHz and 470MHz, mainly for China, Southeast Asia, South America and Eastern Europe. This device is not suitable for use in North America. In the US, 433 MHz is almost in the middle of the 70 cm amateur radio band. By law, only a licensed radio amateur can transmit on this frequency. Anyone transmitting on this frequency without a valid amateur radio license is violating Federal Communications Commission (FCC) rules and faces a hefty fine if caught.

Pros
  • Availability
Cons
  • Long time

Connector IOT/Midrange sensor

Works exactly as intended. But be careful, the distance between the holes on this model is about half that of a regular breadboard. So usually you have to solder pins/wires. However, that's not necessarily a bad thing due to the smaller footprint. The range of the small wire antennas is more than sufficient for a few blocks with thick walls.

  • Pleasant
