Buying a kit isn't everyone's cup of tea. In fact, we see the eChook kit as a first stepping stone to instrumenting a car and hope teams will be able to move on to custom designs to satisfy their needs.

Everything we have created except for the telemetry is open source. This means you can use as much or as little of it as you want in your designs.

If you have PCB etching facilities then designing your own PCB, potentially reusing the eChook circuit schematics to create a custom system might be an excellent project, or if you have an existing data logging board, you may be able to connect a bluetooth module and be able to use the eChook app and telemetry to get some good real time data in the pits. See the Bluetooth Communication section for more details.

For insurance reasons (ugh) we can't give you modifications to make to the eChook if you have bought one of the kits, but we are always happy to answer electronics questions - pop over to the or message us here.

Purchasing the PCBs

If you would like to buy just the PCBs and source the rest of the components yourself, you can now buy these through the eChook store: .
