1. Use a 3D WiFi antenna to save space. We have also reserved the IPEX antenna base for use.

If you want to connect other antennas, you can adjust the resistance as needed, so you can connect other antennas directly. [Note that the integrated antenna and external antenna cannot be used together]

2. The Axp192 power management chip can better maintain the power supply of the entire circuit.

In addition, the product is equipped with an anti-reverse protection circuit to ensure the safety of electricity.

3. The built-in Lora chip SX1276 [868/915 MHz] or SX1278 [433 MHz] makes it easier for the project to send and receive data over long distances with low power consumption.
