Today we will look at a completely new LoRa board. A new Semtech LoRa chip series (SX1261, SX1262, SX1268) and new ASR6501 microprocessor. Is it the best LoRa board ever? And what about the new LoRa chip? Let's have a closer look.
The current LoRa chips from Semtech came to the market in 2013. Earlier this year, they finally announced new chips. So far, we did not see them often on the market. Most used boards still are based on the old chips. Recently, Heltec built this new board using one of these new LoRa chips. To find out if this is the best LoRa board ever, we will:
- Compare the new and the old LoRa chips
- Look at this new module used on this Heltec board
- Check if and how good the Arduino IDE supports it
- Measure the output power of the LoRa chip
- Measure the power consumption and check if it really is "low power"
- And finally, you will get my verdict
