APM2.8 ArduPilot Mega APM 2.8 Multicopter Flight Controller 2.5 2.6 Upgraded

  • Size: 70*45*13.5
  • Weight: 28G
  • APM is an open source flight control, can you play APM well depend on individual ability.
  • Player must have ability of basic understanding of monolithic integrated circuit, c-language, knowledge of electrical,mechanical, and also needs a certain degree of mental capacity, financialand material resources, energy support.If you're not ready, then We recommend that you prepare some introductory information first.
  • Introduction: Eliminate V2.52  Version Old 1.0mm 6P SM06B GPS interface , changed to the DF13-4P compass external I2C interface, Place the DF13-5P GPS interface with external interfaces of the compass, more convenient to connections GPS with external compass.
  • Replaced the V2.52 I2C interface to multi-purpose MUX interfaces, which can be used by the users themselves through the Pad of Back Board freely configurable function output, UART0,UART2,I2C,OSD optional, defaults OSD interface, avoiding 2.52 version when you want to use both Data Transmission and OSD, you need to use Y-line separating the interface programme.
  • Improved OSD interface when used in conjunction with Data Transmission, because of the isolation resistance, more effective to avoid the interference of Data Transmission.
  • New V2.8.0 use United States semi-LP2985-3.3, pressure-resistant up to 16V, increased reliability, reduced probability of Bad Gyro health due to voltage problems.
