Specification

Inputs

  • For benchtop development, the VOXL-ACC-PS or PS-XT60 wall power supplies can be used.

  • J2: 5V DC Barrel Jack Input
    • Switchcraft Inc. RAPC712X, 5A contacts
  • TP3 (+) TP1 (-) XT60 LIPO battery input cable via manual solder pads (XT60 can be changed to anything with a cable)
    • LIPO range 2S-5S [2 cell (6.4V min, 7.4V nom, 8.4V max) 5 cell ( 16V min, 18.5V nom, 21V max)]
      • Note: Absolute max voltage of design is limited to 25V due to capacitor ratings. A 27V zener is present which would clamp anything higher than 27V.

Outputs

  • J1: Molex 4-position 22-05-7045 2.5mm R/A male connector, 3A DC per pin @22 AWG (PCB/wire gauge dependent)
    • Mates with VOXL and VOXL Flight power input connectors via MCBL-00001 or Flight Core via MCBL-00006
      • Pin 1: 5V DC OUT
      • Pin 2: DGND
      • Pin 3: I2C SCL (5V levels)
      • Pin 4: I2C SDA (5V levels)

I/O

  • I2C bus @ 5V SCL/SDA on output connector for reading LIPO and 5VDC Voltage and Current metrics with Qty-2 LTC2946
    • LIPO on I2C ADDR 0xD4, Device U1
    • 5V Output on I2C ADDR 0xD6, Device U2

Operating Range/Environmental

  • Selected to match the hardware designs at the time of 0C to 55C
  • Not designed for dust or moisture ingress protection or solar load protection

AKA

  • May be found referenced as APM or M0009

2D/3D Drawings

Note: These 3D files contain all components on them. Some board configurations do not install “DNI” certain connectors or components. Please refer to the included diagrams and design schematics for more detailed information
