BF6H-M is a low-power embedded Bluetooth audio module that T uya has developed.
It mainly consists of a highly integrated Bluetooth chip (FR8016HA) and a few pe-
ripheral circuits with the Bluetooth communication protocol stack and rich library
functions inside. Based on the support of the Bluetooth intelligent firmware and
protocol stack of the Freqchip, BF6H-M is completely compatible with the Bluetooth
protocol V5.0 Meanwhile, users can develop various application programs on the ba-
sis of the ARM Cortex M3 in the 32-bit high-performance single-chip microcomputer.
In the BF6H-M, audio CODEC, PMU (charger for lithium battery LDO), SPI flashROM
with the XIP mode, IIC, UART, GPIO, ADC, and PWM are integrated into one chip, to
use less power and offer stable connection.
