This DB-RF001 Development Kit consists of a Switch Board and a Motherboard, with two hardware SPI interfaces. The switch board adapts to the common FSK Front-end Modules and LoRa RF Modules. The motherboard integrates a Cortex-M0 32bit MCU (HC32L176KATA from HDSC), and has several common interfaces such as SPI, UART and I2C, while the keys can be used to quickly evaluate the performance of the wireless RF front-end modules.

2 Keys 433MHz LoRa Remote Control with SX1278 chip and long range above 2km, transmitting power is 100mW@3.3V, and receiving sensitivity about -132dBm@0.81Kbps.
