[Introduction]：E35-2G4T27SX is a new-generation 2.4GHz, 20dBm wireless serial port module based on Telink's TLSR8208 chip. It features multiple transmission modes, operates in the 2400-2480MHz frequency band, and utilizes a standard stamp-hole surface-mount package. It also includes a UART communication interface for easy development and use. This wireless module operates in the ISM band and supports wireless transparent transmission, fixed-point transmission, broadcast transmission, serial port upgrades, and communication encryption. Custom development services are also available.
