Resources

Adding a battery

  • My unit did not come with a battery
  • Added an SMT mount ST connector to the board
  • Added an 850 mAh LiPo battery
  • The pinout on the card was backwards from the pinout of the connector at the end of the battery wires
    • Removed the pins from the battery wire connector and flipped the pins
  • Charging works
  • Battery is a bit too thick to screw the back on completely
  • Switched to longer standoffs
  • Someone else's page (they added an inline connector and wired to the card)

Software

Test Jigs

RF Demo Kit

  • AliExpress listing
  • Board
  • SMA female connectors X6
  • 6mm standoffs X4
  • M2.5 screw X4 (for standoffs)
  • 49 pin machine contact array (7x7)
  • (2) 0805 49r9 calibration resistance
    • 1 spare)
    • Installed 49.9 ohm resistor on upper left SMA
    • Installed 0 ohm resistor on upper right SMA (not in kit)
