  • Power Supply
    • USB 5V 120mA
    • Maximum charging current 0.8A


Adding a battery[edit]

  • 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)


Test Jigs[edit]

RF Demo Kit[edit]

  • AliExpress listing
  • Board
  • SMA female connectors X6
  • 6mm standoffs X4
  • M2.5 screw X4 (for standoffs)
  • 49 pin machine contact array (7x7)
