The head of Bittle is designed to be a clip to hold extensible modules. We compiled a sensor pack with some popular modules, but its contents may change in the future. You can also wire other add-ons thanks to the rich contents of the Arduino and Raspberry Pi communities.
You can find the demo codes of these modules in our GitHub repository. They should be in the folder if you download the whole OpenCat repository.
You can also purchase the following third-party sensors (such as Seeed studio):
(Applicable to Nybble)
The loudness and light level modules can generate for the corresponding signals and should be connected to the analog Grove socket.
The touch, reflection, PIR sensors can generate digital 1 or 0 as a switch signal. So they should be connected to the digital Grove socket. In the , we use the fourth socket with D6 and D7.
The , , and module should be connected to the I2C Grove socket.
