radio frequency chip solution,Based on 's third-generation LR1121 RF chip design, it supports 150-960MHz (sub-GHz) and 2.4GHz bands and provides advanced dual-band communication capabilities. One receiver can meet the needs of two frequency bands at the same time. High-performance ESP32-C3 chip,Equipped with a 32-bit RISC-V single-core processor with a main frequency of up to 160MHz, it can provide efficient computing power and fast response speed. 915M+2.4G dual-band antenna,The 915M+2.4G dual-band T-shaped antenna is custom-developed for dual-band receivers. It has good reception performance at both 915MHz and 2.4GHz. When the dual-band receiver switches the working frequency band, there is no need to replace the antenna, which is more convenient to use. Built-in temperature compensated crystal oscillator (TCXO),Using TCXO temperature compensated crystal oscillator, no fear of extreme temperature such as high and low temperature affecting the working state, the frequency is more stable, and the flight is . 100mW return power.
