[Interface]:USB
[Frequency band]:400MHz
[Function]:Used to quickly evaluate and test the E42-400M20S wireless module.
[Introduction]:E42-400MBL-01 development evaluation kit is designed to help users quickly evaluate the E42-400M20S wireless RF module. Most of the pins on the development evaluation board have been led out to pin headers on both sides. Developers can easily connect various peripheral devices through jumpers according to actual needs. This development board kit provides complete software application examples to help customers quickly get started with wireless data communication development. For module functions, please refer to the E42-400M20S user manual.
