Griptonite Motherboard

The Griptonite Motherboard is a force-sensing hangboard with configurable LEDs (green, red, orange) and real-time force streaming. It supports battery, firmware/hardware info, calibration, and session export.

Basic usage

import { Motherboard } from "@hangtime/grip-connect"

const device = new Motherboard()
device.notify((data) => console.log(data.current, data.peak))

await device.connect(
  async () => {
    console.log("Battery:", await device.battery())
    await device.stream(30000)
    device.download("json")
    device.disconnect()
  },
  (err) => console.error(err),
)

Methods

Motherboard supports all shared methods (connect, disconnect, isConnected, notify, active, read, write, tare, download). See Device interface for details.
