Chapter 1 Product Overview
1.1 Product introduction
E70-433T series is a wireless serial port module (UART) based on TI's CC1310 (built-in dual-core ARM) radio frequency
chip, which can work in the 431-446.5 MHz frequency band (default 433MHz), GFSK modulation method, TTL level output,
3.3V IO port voltage; this product adopts 24MHz industrial-grade crystal oscillator to ensure its industriality and stability.
The module has data encryption and compression functions, and the data transmitted by the module in the air is random,
and the data interception is meaningless through strict encryption and decryption algorithms. The data compression function
has the possibility to reduce the transmission time, reduce the probability of being interfered, and improve reliability and
transmission efficiency.
The factory has built-in low-power multi-function wireless serial port program, and users can also carry out secondary
development according to their needs.
