General description
The RF04 is an ultra-low-power system on-chip(SoC), a Bluetooth chipset, integrated with 32-bit MCU for Bluetooth 5.0 low energy(BLE 5.0) applications which shows the great performance of a leading RF transceiver with low-power consumption. It meets the challenges of a broad range of applications that need advanced Bluetooth LE features.
Also Bluetooth mesh can be run concurrently with Bluetooth LE, enabling smartphones to configure and control mesh nodes.
In this Bluetooth LE device, several digital and analog peripheral interfaces are optimized for external control, including GPIO, SPI, UART, IIC, PWM, ADC, and LDOs.
