Specification

Part Numbers

This is available in three variations, depending on the cable you need:

• MKIT-00028-1 - Power Module v3, heat shrink, and cable for VOXL or VOXL Flight (MCBL-00001)
• MKIT-00028-2 - Power Module v3, heat shrink, and cable for Flight Core (MCBL-00003)
• MKIT-00028-3 - Power Module v3, heat shrink, and cable for VOXL + Flight Core (MCBL-00011)

Inputs

• XT60 LIPO battery input cable via solder pads (XT60 can be changed to anything with a cable, positive on V+IN pad or BAT_IN 0.025” hole, negative on GND pad or 0.025” hole)
  • LIPO range 2S-6S [2 cell (6.4V min, 7.4V nom, 8.4V max) 6 cell ( 19.2V min, 22.2V nom, 25.2V max)]
    • Note: Absolute max voltage of design is limited to 30V due to D1 zener diode which would clamp anything higher than 30V.

Ouputs

• XT60 LIPO battery cable output via solder pads ((XT60 can be changed to anything with a cable, positive on V+OUT pad or BAT_OUT 0.025” hole, negative on GND pad or 0.025” hole)
• J1: Molex 4-position 22-05-7045 2.5mm R/A male connector, 3A DC continuous per pin @22 AWG (PCB/wire gauge dependent) 6A capable regulator.
  • Mates with VOXL and VOXL Flight power input connectors via MCBL-00001 or Flight Core via MCBL-00006
    • Pin 1: 5V DC OUT
      • Contact ModalAI for alternate voltage outputs, custom DC voltage outputs may impact LIPO input operational range
    • Pin 2: DGND
    • Pin 3: I2C SCL (5V levels)
    • Pin 4: I2C SDA (5V levels)
      • Note: Alternate DC voltage outputs above 5V will not impact 5V I2C levels due to dedicated regulator for INA231 devices. Alternate DC voltage outputs below 5V (example 3.3V) will make I2C voltage levels scale lower accordingly (i.e.: ~3.3V).

I/O

• I2C bus @ 5V SCL/SDA on output connector for reading LIPO and 5VDC Voltage and Current metrics with Qty-2 INA231
  • LIPO on I2C ADDR 0x44, Device U3
  • 5V Output on I2C ADDR 0x45, Device U4

Operating Range/Environmental

• 0C to 55C non-condensing
• Not designed for dust or moisture ingress protection or solar load protection (no IPxy rating)
• Heatshrink over design recommended for short protection from other electronic components

AKA

• May be found referenced as APM Lite or M0041

2D/3D Drawings

• Dimensions: 21.6mm x 28.75mm
