Features: Brand new and high quality Using the new generation of SX1262 RF chip, provides better performances than the SX127X series in power consumption, communication distance and power efficiency. Adopts modulation technology to solve the problem in the traditional design solution which can not balance distance, anti-interference, and power consumption at the same time. Double cores M0+ processor, flexible clock running up to 133MHZ.264KB, and 2MB of onboards Flash memory. Onboards FPC 8PIN connector, adapting USB Type C port via adapter board.Castellated module allows soldering direct to carriers boards. USB 1.1 with devices and host support.Low-power sleep and dormant modes. programming using mass storage over USB, up to 20X multi-function GPIO pins. Supports GFSK modulation, featuring better anti-blocking and long distance communication.With -148dBm high reception sensitivity and programmable emit power to 22dBm. Supports preambleS detection, up to 256 bytes data packet engine.Comes online resources and manual (example in C) Specifications: Material:PCB Type:A-LF/AHF/B-LF/BHF Size:Approx.21x41mm/0.82x1.61inch Note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
