Let me baptise this category with a thread to talk about some high power 433MHz LoRa modules I’d like to test.
The ones that seem interesting are:
E22 (UART) http://www.ebyte.com/en/product-view-news.aspx?id=939
E22 (SPI) http://www.ebyte.com/en/product-view-news.aspx?id=454
E62 (Full Duplex?) http://www.ebyte.com/en/product-view-news.aspx?id=224
I excluded the E32 as it uses the older SX1278 module while the E22 mounts the newer SX1268. Looking at the datasheet, the range tests were performed with different data rates, which justifies the extra kilometers (8 vs 12km) of the SPI version.
Same specs, different marketing strategy?
Going to the E62, the datasheet reports
Module E62-433T30D is a full-duplex wireless transceiver module with TTL level output, operates at 425-450MHz (default: 433MHz) […]
Features TDD (Time Division Duplex). User can transmit data while receiving, not have to wait for the end of receiving
I am not aware of any similar full duplex LoRa implementations, although concurrent TX/RX can be faked by the UART internal buffering.
If you have already tried one of these modules let me know.
