1 Product Overview
1.1 Brief Introduction
E70-900M14S1B adopts the original imported CC1312R from Texas
Instruments (TI). It integrates a single-chip microcomputer and wireless transceiver,
and uses a 48MHz industrial-grade high-precision low-temperature drift crystal
oscillator to ensure its industrial characteristics and stable performance.
The CC1312R chip has a built-in powerful 48MHz Arm Cortex-M4F
processor, and has abundant peripheral resources such as UART, I2C, SPI, ADC,
DMA, and PWM. The module leads to all the IO ports of the single-chip
microcomputer, which can be used for multi-directional development.
Since the E70-900M14S1B is a pure hardware SOC module, there is no program at the factory, and the user needs to develop it
again before it can be used.
