Introduction to hardware resources

  The hardware is mainly composed of three parts , They are unmanned aerial vehicles 、 Remote control handle and cocobit Programming board .

2.1 Introduction to UAV

  The complete UAV is shown in the figure below .

chart 1
  The main core of UAV is ARM Cortex-M3 High performance single chip microcomputer with kernel —— Italian semiconductor STM32F103CBT6, Main frequency up to 72MHz、RAM the height is 20kByte、Flash the height is 128kByte.
  The top of the UAV RGB The lantern box contains icm20602（ Six axis sensors ）+SPL06（ barometer ） Composed of IMU unit （ Inertial measurement unit ） and WS2812 Of RGB Lantern unit .
  The drone motherboard is made of four layers of gold sinking high-quality fiberglass , On the mainboard of the UAV, there are not only STM32F103CBT6 The main core , It also carries two chips AO9926C double N Ditch MOS As the driving unit of UAV motor , In addition, the motherboard also integrates NRF24L01 2.4G Transceiver chip , As the communication unit of UAV , There is also TC4056 As power management chip , For charging management of UAV .
  The main board of the UAV is fixed on the carbon fiber bracket by screws , The four corners of the carbon fiber support are placed with four big power 8520 Hollow cup motor ,8520 The hollow cup motor is connected with four ABS High toughness rotor .
  Below the carbon fiber bracket is the battery slot , Below the battery slot is the optical flow module 、 Vision module and laser module 2 individual （ One of them is reserved , It can be used to avoid obstacles ）.
  The interfaces on the UAV motherboard are shown in the figure below .

2.2 Introduction to remote control handle

  The remote control handle of UAV is also an important part of the whole flight control system , The remote control handle adopts ergonomic shape , use FR-4 Gold sinking process ; The main core of the remote control handle is ARM Cortex M3 High performance single chip microcomputer with kernel —— Italian semiconductor STM32F103C8T6, Main frequency up to 72MHz、RAM the height is 20KByte、Flash the height is 64KByte.
  The remote control handle is not only equipped with a high-performance main core STM32, There are also high-quality safe power management chips TC4056, Like the drone motherboard, it can pass USB Port to charge the battery , The charging state is fed back through the indicator ; Above the main core is the power enhanced 2.4G Transceiver module , Support ultra long distance data transmission ; Both ends of the remote control handle are rocker bars, which can be used to control the UAV , Below the left rocker is “ Programming model ” Key , coordination cocobit Programming board , It can realize autonomous cruise of UAV . Below the right rocker is “ Emergency stop ” Self locking button , Realize the emergency stop and landing of UAV . The figure below shows the overall schematic diagram of the UAV remote control handle .

2.3cocobit Introduction to programming board
  Shell shell plate (cocobit) It is a graphic programming hardware board designed by crazy shell team for teenagers , Only credit card size . Shell shell plate (cocobit) Support graphical drag and drop programming , Users can drag and drop logical blocks through the upper computer software , The upper computer software can automatically convert the logic block dragged by the user into the corresponding C Language code and compiled into executable hex file .
  Shell shell plate (cocobit) Although it looks like a small hardware board , But it supports rich hardware expansion , such as ： take cocobit As the core of the brain, the programming machine car / Programming electronic building blocks / Programming robot / Programming drones and so on . ad locum , We will cocobit Insert the hardware board into the remote control , adopt cocobit Graphical programming software , The aircraft can be programmed to fly autonomously , Let the plane fly according to our planned route .
  cocobit Adopt high quality FR-4 Sunken gold black oil material , Carrying Atmel The company's 8 Bit high performance chip ATmega328P as well as Dialog The company's high-performance and the lowest power consumption in the world BLE SOC chip DA14580 Dual core , Support bluetooth 4.0. meanwhile cocobit Also carry the 6 Shaft sensor MPU6050, stay cocobit The other side of is also integrated 7*7 Of LED Dot matrix and four buttons ,cocobit Use gold fingers to lead out common interfaces , Cooperating with the host computer and external resources, it can perfectly realize many experiments of physical programming in Engineering Physics . As shown in the figure below cocobit Front view of 、 Reverse view .
