RP2040 microcontroller chip designed with for Equipped with dual-core ARM M0+ processor, running frequency up to 133MHz flexible clock Built-in 264KB and 2MB on-chip Flash Onboard FPC8PIN interface, USB Type-C interface can be led out through the adapter board Stamp hole design can be directly welded and integrated into the base plate designed by the user. USB1.1 host and device support. Supports low-power sleep and hibernation modes RP2040-LORA-HF The frequency of HF version is 850-930MHz, suitable for Europe, America and Oceania. RP2040-LoRa is a LORa development board using the SX1262 radio frequency chip. It performs the SX127X series in terms of power consumption, transmission distance, power efficiency and other performances. LORa modulation technology solves the problem that traditional design solutions cannot take into account distance, anti-interference and power consumption at the same time. The problem. In addition, combined with the LoRa gateway, it can be connected to TTN, ChirpStack and other servers to conveniently and quickly verify the LoRa network cloud service. Can be recognized as mass storage via USB for drag-and-drop downloading of programs, up to 20 multi-function Capable GPIO pins Supports FSK, GFSK, LORa modulation methods, better anti-blocking and ultra-long distance communication characteristics High receiving sensitivity as low as -148dBm and programmable transmit power up to 22dBm Supports preamble detection, packet engine with , up to 256 bytes The appearance and color of different batches of products may be different, which not affect the use.
