Ultra thin color screen paperless recorder

1、 Overview of Ultra Thin Color Screen Paperless Recorder Products
The TXR7000 series ultra-thin color screen paperless recorder adopts a high-performance ARM Cortex-M3 32-bit RISC core and a large capacity parallel NAND FLASH memory chip to store historical data. The serial FRAM storage chip stores key information such as system configuration parameters, which can simultaneously achieve multi-channel signal acquisition, recording, display, and multi-channel alarm.
