Function:

• Product of Dialog Semiconductor.
• Initially understand the newsletter electronic DA14580 Bluetooth development board
• Introduction of SDK
• Construction of the development environment
• GPIO Marquee
• Serial port application
• Timer application
• ADC application
• DA14580 starts from external SPI FLASH
• Bluetooth serial port high speed transparent transmission

Parameter:

• The regular company products, exquisite workmanship, reasonable design, in line with the use of engineers.
• All IO ports are exported.
• Efficient PCB antenna with support for 15 meters communication distance.
• The current test port is reserved, and the auxiliary circuit and the BLE circuit are respectively powered to facilitate accurate evaluation of the current consumption of the BLE system.
• The design is reasonable, the development board provides a fixed column, and the partners are no longer worried that the development board will be unstable.
• Three power supply modes, USB, CR2032 button battery, 3.7V lithium battery.
• Onboard 6.8V boost circuit, the development board can burn OTP, both internal and external.
• Onboard buzzer for user alarm needs.
• A 4-wire JLINK SWD debug interface (including VCC) is reserved, and an external JLINK can be used to supply power.
• Shipped a MICRO USB cable for Android phones and several DuPont lines.
• Onboard CP2102 USB to serial port chip, a MINI USB data cable to complete development board power supply and program download, support Bluetooth transparent transmission.
• The development board reserves the SWD debug interface (the simulation needs to purchase JLINK separately).
• Externally expand a FLASH, support repeated erasing, support FLASH boot.
• Onboard relays and high-voltage binding posts can be used by users to develop smart homes .
• The board has three user buttons and two user LEDs .
• A single RGB colorful LED to make the most of your creativity.
• The ultra-small module + base plate has a split structure for easy replacement and upgrade.
• In addition, DA14583 and DA14585 modules are available, which can replace the current DA14580 module .
• Low power TX: 3.4 mA, RX: 3.7 mA
• With serial port function, you can use the Smart Snippets to burn the program, or you can use the serial port of the DA14580 to connect to the PC for easy debugging .
• Onboard lithium battery charging circuit.
