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.

FSK Transceiver module with Si4463chip, low-power, long-distance

The DL-RXC2219A/B is an ultra-low power, high performance, OOK and (G)FSK receiver 868 MHz wireless applications. includes a complete line of transmitters, receivers and transceivers. All features can be configured either by off-line EEPROM programming or on-line registers writing. The configuration file to be written, into the registers is generated by the smart RF PDK.

FSK Transceiver module with Si4432 chip, long-distance (1.8km) wireless transceiver module with receiving sensitivity of -121dbm.

DL-RTA7139 was designed base on AMICCOM A7139 wireless transceiver chip from Taiwan. It is a compact and low power wireless transceiver module, mainly set to 315/433/470/868/915/MHz ISM/SRD frequency bands

Designed base on Silicon Labs' Si4463 wireless transceiver chip. It is a compact, long-distance RF transceiver module with power amplifier with sensitivity up to -124dbm.
