04Jacdac_Modules

Overview​

Jacdac is a plug-and-play hardware and software stack for microcontrollers and their peripherals such as sensors and actuators. Jacdaptors allow Jacdac to integrate with micro:bit, Raspberry Pi, and other ecosystems.

Key Features:

  • All Jacdac hardware utilizes a universal driver interface. Regardless of manufacturer or device type, users can seamlessly access compatible programming blocks within supported IDEs.

Connecting to micro:bit​

If using Jacdac modules with your micro:bit for the first time, we recommend first downloading a blank program with the Jacdac extension to your micro:bit. This allows real-time detection of connected Jacdac devices and enables viewing sensor values/controlling modules via the simulator

Click "Connect Device", follow the prompts to complete micro:bit connection. Once done, click the adjacent "Download" to flash the blank program (with Jacdac extension) to the micro:bit.

After downloading, you'll see the corresponding Jacdac module in the hardware simulator. If you unplug or connect a Jacdac module, the simulator will automatically remove or add it accordingly.

While the Jacdac module appears in the simulator and allows viewing/control, its corresponding blocks won't yet appear in the toolbox. Click "Add Blocks" in the simulator to import the module's blocks into the toolbox.

Jacdac coding​

Jacdaptor​

The Jacdaptor for the micro:bit V2 allows Jacdac modules to be connected to the micro:bit and coded using MakeCode.The power switch has two options: "Jacdac" and "micro:bit".

![Jacdaptor2 ](E:\kittenbot_work\magicai\instructions_new\assets\Jacdaptor2 .png)

For micro:bit-powered projects (typically during debugging): Slide the switch downward to the "Jacdac" position → micro:bit powers the Jacdac system.

For external power modules (standalone operation without PC): Slide the switch upward to the "micro:bit" position → Jacdac powers the micro:bit.

Jacdac-Power​

Drive your high-demand JACDAC components with confidence, courtesy of the Power module. Integrated overcurrent protection guarantees a smooth power delivery up to a robust 1A.

Power1

Powering Your Project:

1.Connect any Jacdaptor port to the Jacdac Cable

2.Plug in a Type-C cable or battery pack

3.Flip the switch to "ON" position

Jacdac-Hub​

Integrate modules with finesse using Hub, a comprehensive passthrough hub sporting six versatile connectors.Connect all Jacdac modules to the Jacdac-Hub using Jacdac Cables, then link the Jacdac-Hub to the Jacdaptor.
