SmartElex E220-400M30S 433MHz Breakout Board

E220-400M30S is 1W module developed independently based on new generation of LoRaTM RF chip LLCC68 from Semtech. LLCC68 is suitable for 433MHz and 470MHz SMD wireless module and uses industrial 32mhz crystal oscillator. The original imported LLCC68 is used as the core of the module, a power amplifier (PA) and a low noise amplifier (LNA) are built on the original basis, so that the maximum transmission power reaches 1W and the receiving sensitivity is further improved. In the overall communication Compared with products without power amplifier and low noise amplifier, the stability is greatly improved. Compared with the previous generation of LoRaTM transceivers, the anti-interference performance and communication distance have been improved, further opening the gap with FSK and GFSK modulation products. The product can cover an ultra-wide frequency range of 410~493MHz. Because the module is a pure RF transceiver module, it needs to use MCU driver or special SPI debugging tool. Noted: For more technical information, refer the datasheet in Attachments.
