Suzhou Pairlink Network Technology Co.,Ltd. Buffalo-D5 UserManual 1.Functional Characteristics Buffalo-D5 is SOC module developed based on the Bluetooth 5.0 standards. the internal integration architecture ARM Cortex-M0 processor.It has the advantage of small volume, low power consumption, long distance transmission, strong anti-jamming capability, low cost.Specifically applied to Bluetooth low power control area,and suitable for various occasions short distance wireless communication. Buffalo-D5 integral compact, simplifies the design in hardware and institution for user. The module interface open completely to make the users has more flexible secondary development space. The Buffalo-D5 has a standard 2-wire uart interface (RX and TX) and has adjustable baud rates up to 1MBd. The Buffalo-D5 integrates a universal asynchronous receiver/transmitter that support much of the functionality of the industry-standard 16550 UART. Both high and low baud rates can be supported by 16 MHz system clock. The Buffalo-D5 UART operates correctly with the host UART as long as the combined baud rate error of the two devices is within 5%. 1.1.Product feature Buffalo-D5 Supported AT Command Protocol, could be easily porting into different MCU controllers. 1: Buffalo-D5 under Bluetooth 5.0 specification. 2: Very small current consumption. 3: On chip OTP, and also easy to extend EEPROM/SPI Flash. 1.2. Main Application domain. 1MCU data pass-through. 2Bluetooth printer / Scanner / Digital price tag etc. 3Remote control / Keyboard and mouse / Toys / Smart phone self timer etc. 4Industrial remote control / Industrial telemetry / Industrial data collection. 5Smart home / Intelligent lighting / Intelligent access control system.
