Good value for learning wireless comms
As a student, this board offers great value to learn about different RF protocols. The only downside is that the onboard LED is a bit dim, but that's a minor issue. The community support for ESP32 is huge which helps a lot.

Great hardware, documentation could be better
The build quality is solid and the pinout is standard enough to work with most breadboards. However, finding specific examples for the LR1121 geolocation features took some digging in the forums. Once set up, it works flawlessly.

Robust for industrial testing
We are using these for preliminary testing of our factory monitoring system. The ability to switch between Wi-Fi for local config and LoRa for long-range telemetry is a game changer. Very reliable so far.

Perfect for LoRaWAN Gateway Projects
This board is exactly what I needed for my smart agriculture sensor network. The integration of Wi-Fi, Bluetooth, and LoRa on a single ESP32-S3 chip makes prototyping incredibly fast. The LR1121 chipset handles multi-band scanning effortlessly.

Excellent range and stability
I replaced an older module with this one and saw immediate improvements in signal stability. The dual-core processor handles the network stack without lagging. Highly recommended for industrial control prototypes.

Seamless ESP-IDF Integration
Flashed the latest ESP-IDF version without any hiccups. The USB-C port provides stable power delivery even when driving multiple peripherals. The PSRAM size is generous for handling large data buffers.
Q: Does this board support LoRaWAN Class A and Class C?
A: Yes, the LR1121 chipset on this board fully supports LoRaWAN Class A and Class C device classes, configurable via the ESP-IDF or Arduino libraries.
Q: Does the LR1121 support GNSS/GPS functionality?
A: Yes, the LR1121 includes a passive GNSS scanner capable of detecting GPS, Galileo, Beidou, and GLONASS signals for low-power geolocation services.
Q: Is there a built-in debugger or do I need an external one?
A: This board features a built-in USB-to-UART bridge for flashing and serial monitoring. For advanced JTAG debugging, you may still prefer an external probe, but basic development requires no extra hardware.
Q: Can I power this board directly via the GPIO pins?
A: It is not recommended to power the board directly via GPIO pins due to current limitations. Please use the USB-C port or the dedicated 5V/GND pins for stable operation.
Q: What antennas are compatible with the IPEX connector?
A: Any standard IPEX/U.FL antenna matching the frequency bands you intend to use (Sub-GHz or 2.4GHz) will work. Ensure the impedance is 50 ohms for optimal performance.
