Waveshare LoRa Development Board Kit Based on Raspberry Pi RP2040 Microcontroller Chip, Integrate SX1262 RF Chip, 850~930MHz Frequency, Programmable Emit Power up to 22dBm, Long-Range Communication

Overview RP2040-LoRa-HF is a LoRa development board using the new generation of SX1262 RF chip, provides better performance than the SX127X series in power consumption, communication distance and power efficiency. Adopts LoRa modulation technology to solve the problem in the traditional design solutions which can not balance distance, anti-interference, and power consumption at the same time. RP2040 microcontroller chip designed by Raspberry Pi in the United Kingdom Dual-core Arm Cortex M0+ processor, flexible clock running up to 133 MHz 264KB of SRAM, and 2MB of onboard Flash memory Onboard FPC 8PIN connector, adapting USB Type-C port via adapter board Castellated module allows soldering direct to carrier boards USB 1.1 with device and host support Low-power sleep and dormant modes Drag-and-drop programming using mass storage over USB, up to 20 x multi-function GPIO pins Supports FSK, GFSK, LoRa modulation, featuring better anti-blocking and ultra-long distance communication With -148dBm high reception sensitivity and programmable emit power up to 22dBm Supports preamble detection, with CRC, up to 256 bytes data packet engine Comes with online resources and manual (example in C)
