NodeMCU-BU01 개발 보드 BU01 UWB 실내 포지셔닝 LDO 모드 위치, 초광대역 단거리 고정밀 범위 설정 - AliE

회사에서는 AliExpress라는 사이트에서 NodeMCU-BU01 제품을 구매하였다. 더 자세한 정보는 가치창조기술이라는 사이트에서 확인할 수 있었다. 가격은 거의 두 배 정도 차이가 나는 것 같다.

  IO7: The default value is used as SYNC input. This pin can be reconfigured as a general-purpose I/O pin GPIO7 under software control.
  IO6: General purpose I/O pin. At power-up, it is used as the SPIPHA (SPI phase selection) pin for configuring the SPI operating mode. After power-up, this pin will default to a general-purpose I/O pin.
  IO5: General-purpose I/O pin. At power-up, it is used as the SPIPOL (SPI polarity selection) pin for configuring the SPI operating mode. After power-up, this pin will default to a general-purpose I/O pin.
  IO4: General purpose I/O pin.
  IRQ: Interrupt request output from DWM1000 to host processor and connected to PB0 of MCU. By default, IRQ is an active high output, but if necessary, it can be configured as active low. In order to operate correctly in SLEEP and DEEPSLEEP modes, it should be configured for active high operation. This pin will float in sleep and DEEPSLEEP states, unless it is pulled low, it may cause a spurious interrupt. When the IRQ function is not used, this pin can be reconfigured as the general-purpose I/O line GPIO8.
  CLK: SPI clock and connected to PA5 of MCU
  MISO: SPI data output and connect to PA6 of MCU
  MOSI; SPI data input and connected to PA7 of MCU
  CSN: SPI chip select and connect with PA4 of MCU. This is an active low enable input. A high-to-low transition on SPICSn indicates the start of a new SPI transaction. SPICSn can also be used as a wake-up signal to make DW1000 exit sleep or sleep state.
  PA3: PA3 on MCU
  PB1: PB1 on the MCU
  PB10: PB10 on MCU
  PB11: PB11 on MCU
  LED1: PA2 on MCU, connect to LED1
  LED2: PA1 on MCU, connect to LED2
  BTN: PA0 on MCU, connect to BTN button
  RESET: Reset pin on MCU, connected to reset button
  GND: Ground
  GND: Ground
  V3.3: 3.3V power supply
  V5 5V: power supply
  V3.3: 3.3V power supply
  GND: Ground
  VBAT: MCU battery power supply Vbat
  SCL: The SCL pin on the MCU, the default is to pull up 3.3V, and the sensor SCL pin is internally connected
  SDA: SDA pin on MCU, 3.3V is pulled up by default, internal sensor SDA pin
  PB8: PB8 on MCU
  PB9: PB9 on MCU
  PB5: PB5 on MCU
  PB4: PB4 on the MCU
  PB3: PB3 on the MCU
  PA15: PA15 on MCU
  V3.3: 3.3V power supply
  RST: Reset pin on BU01 and connected to PB12 of MCU
  WAKEUP: Wake-up pin on BU01 and connected to PB13 of MCU. When set to active high state, WAKEUP pin brings DW1000 from sleep or DEEPSLEEP state into working mode. If not used, this pin can be grounded
  EXTON: The EXTON pin on BU01 is connected to PB14 of MCU, and the external device is enabled. Set during the wake-up process and remain active until the device enters sleep mode. Can be used to control external DC-DC converters or other circuits that are not needed when the device is in sleep mode to minimize power consumption
  U1RX: UART1-RX on MCU
  U1TX: UART1-TX on MCU
  PA8: PA8 on MCU
  PB15: PB15 on MCU
