DB-RF001, Development Kit for Wireless Modules

Brief Introduction

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. It was low power consumption designed and can support battery power supply, which is convenient to evaluate an RF module before project officially launched.

Product Features

● Convenient to operate, you can simply evaluate the RF module and test its communicationdistance; 

● Supports KEIL secondary development, for a deep testing; 

● Schematic Diagram, Demo Code, Data Sheet, User′s Guide can be provided; 

● Convenient debugging: SWD download port, UART serial port output with USB to TTLfordebugging; 

● Two hardware SPIs and one hardware UART, with just one RF Switch Board for multipleRFmodules. 

● KEY1, KEY2 keys and LED 1, LED 2 lights for user interaction.
