Product Details
A28-T2G4A12D1a is an industrial-grade, high-stability wireless data module operating in the 2.4 GHz band with 15 mW (12 dBm) output power. Developed with the Semtech SX1281 RF chip, it supports eight UART baud rates ranging from 1200 to 115200 bps. In Continuous Transmission mode, the wireless air speed automatically adapts to match the UART baud rate; in Non-Continuous mode, the air speed is user-configurable. Select baud rate and air speed combinations support unlimited packet length Full-Duplex transmission.
The module operates in three distinct working states, allowing seamless switching during runtime to optimize performance for various application scenarios.
