Excellent Range
Testing the LoRa range compared to SX1276 modules and this performs significantly better in urban areas.

Good value
Power consumption is reasonable for a dual wireless board. USB-C is a nice touch for modern setups.

Perfect for LoRaWAN Gateways
Exactly what I needed for my home automation hub. The LR1121 chip works flawlessly with the ESP32-S3.

Great board, docs could be better
Hardware is solid and compact. Wish there were more example sketches for the LoRa part specifically.
Q: Can I power this with 3.3V directly?
A: Yes, but ensure stable power supply. USB-C 5V is recommended for stability during transmission.
Q: Does this support EU868 frequency?
A: Yes, the LR1121 supports global frequencies including EU868 and US915 bands.
Q: Is an antenna included?
A: No, please purchase a compatible 2.4GHz/LoRa antenna separately with IPEX connector.
Q: Does it support LoRaWAN Class C?
A: Yes, the firmware supports Class A, B, and C depending on your library implementation.
Q: Compatible with Arduino IDE?
A: Yes, install the ESP32 board manager package and select ESP32S3 board.
