E220 LoRa series module test board Wireless data communication development Kit Wireless data transmission anti-interferen
[Interface]: USB
[Product weight]:152.6±0.1g
[Working frequency band]:900MHz
[Introduction]:The MBL series evaluation kits are designed to help users quickly evaluate Ebyte's next-generation package-compatible wireless modules. Most of the pins on the board are led out to the pin headers on both sides, making it easy for developers to connect a variety of peripherals via jumpers to their needs.
