Q: What is the main advantage of the 33dBm version of E290?
A: The 33dBm (2W) output power is double that of standard 30dBm modules. This provides much stronger signal penetration through obstacles like concrete walls and foliage, ensuring a stable link where lower-power modules might fail.
Q: How does ChirpIoT™ modulation help in noisy environments?
A: ChirpIoT™ uses advanced spread spectrum techniques that allow the signal to be decoded even when the noise floor is higher than the signal level. It is highly resistant to jamming from common wireless devices.
Q: Can I use this module with an ESP32 or STM32?
A: Yes. The module communicates via a standard 4-wire SPI bus. It is compatible with any microcontroller that supports SPI, including ESP32, STM32, Arduino, and more.
Q: Is a special antenna required for 2W transmission?
A: Due to the high 2W power, we strongly recommend using a high-gain antenna (like a whip or sucker antenna) matched to 433/470MHz. Ensure the antenna is connected before transmitting to prevent damage to the RF power amplifier.
Q: What is the power supply requirement for this module?
A: The module requires 3.3V–5.5V. At max 33dBm power, the peak current can reach 1200mA. Ensure your power supply can handle this current spike to maintain a stable transmission.
