Running ArduPilot's AP_Periph firmware on an STM32L431 microcontroller, it turns supported UART, I²C, SPI and GPIO devices into native DroneCAN peripherals, which simplifies wiring while making the system more reliable and easier to extend.\u003c\/p\u003e\n\u003cp\u003eIt will talk to supported GNSS receivers, compasses, barometers and airspeed sensors, and it also offers PWM outputs, buzzer and LED notification, and battery voltage and current monitoring over the DroneCAN bus. Three UARTs, I²C, SPI, four ADC inputs and five PWM outputs make it well suited to building custom DroneCAN peripherals or folding existing sensors into an ArduPilot CAN network.\u003c\/p\u003e\n\u003cp\u003eDual JST-GH CAN connectors make daisy-chaining straightforward, and firmware updates go through the DroneCAN GUI Tool, so the CAN Node L431 suits UAV builders and developers alike when extending an ArduPilot-based aircraft.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eConverts supported peripherals into DroneCAN devices using ArduPilot AP_Periph firmware\u003c\/li\u003e\n\u003cli\u003eCompatible with supported GNSS, compass, barometer and airspeed sensors\u003c\/li\u003e\n\u003cli\u003eSTM32L431 MCU with 256KB Flash memory\u003c\/li\u003e\n\u003cli\u003eDual JST-GH DroneCAN connectors for simple network integration\u003c\/li\u003e\n\u003cli\u003e3 × UART interfaces\u003c\/li\u003e\n\u003cli\u003e1 × I²C interface\u003c\/li\u003e\n\u003cli\u003e1 × SPI interface\u003c\/li\u003e\n\u003cli\u003e4 × ADC inputs for battery voltage and current monitoring\u003c\/li\u003e\n\u003cli\u003e5 × PWM outputs\u003c\/li\u003e\n\u003cli\u003eGPIO output with buzzer\/LED notification support\u003c\/li\u003e\n\u003cli\u003eSupports firmware updates via DroneCAN GUI Tool\u003c\/li\u003e\n\u003cli\u003eCompact 26 × 26mm design weighing just 3.7g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMCU: STM32L431xC (256KB Flash)\u003c\/li\u003e\n\u003cli\u003eCAN Protocol: DroneCAN\u003c\/li\u003e\n\u003cli\u003eCAN Data Rate: Up to 1Mbit\/s\u003c\/li\u003e\n\u003cli\u003eCAN Connectors: 2 × JST-GH 4-pin (parallel)\u003c\/li\u003e\n\u003cli\u003eUART: 3 UART1: General purpose UART2: MSP (default), DFU UART3: GPS (default)\u003c\/li\u003e\n\u003cli\u003eUART1: General purpose\u003c\/li\u003e\n\u003cli\u003eUART2: MSP (default), DFU\u003c\/li\u003e\n\u003cli\u003eUART3: GPS (default)\u003c\/li\u003e\n\u003cli\u003eI²C: 1\u003c\/li\u003e\n\u003cli\u003eSPI: 1\u003c\/li\u003e\n\u003cli\u003eADC Inputs: 4\u003c\/li\u003e\n\u003cli\u003ePWM Outputs: 5\u003c\/li\u003e\n\u003cli\u003eGPIO: 1 (TIM16 buzzer output)\u003c\/li\u003e\n\u003cli\u003eDebug Interface: SWD\u003c\/li\u003e\n\u003cli\u003eInput Voltage: 4.5–5.5V\u003c\/li\u003e\n\u003cli\u003eCurrent Consumption: Approx. 40mA\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -20°C to +80°C\u003c\/li\u003e\n\u003cli\u003eDimensions: 26 × 26 × 6mm\u003c\/li\u003e\n\u003cli\u003eWeight: 3.7g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIn the box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 × Matek AP_Periph CAN Node L431\u003c\/li\u003e\n\u003cli\u003e1 × JST-GH 4-pin to JST-GH 4-pin 20cm cable\u003c\/li\u003e\n\u003cli\u003e1 × JST-GH 6-pin to JST-GH 6-pin 20cm cable\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TBS","offers":[{"title":"Default Title","offer_id":58941159145804,"sku":"RX-CAN-L431","price":15.9,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1087\/9952\/5196\/files\/Matek-AP_Periph-CAN-Node.jpg?v=1790286349","url":"https:\/\/dronepart.co.uk\/products\/matek-ap-periph-can-node-l431-dronecan-peripheral-interface-board","provider":"My Store","version":"1.0","type":"link"}
