== Connectors ==
The CANSAT-BASE features many GROVE connectors and a Qwiic/StemmaQt connector.
They can be used to make the connections easy.
=== I2C connectors ===
Among all the connections, the most important are the sda & scl signal attached to the I2C bus.
The SDA (Serial Data) and SCL (Serial Clock) are used to ship back and forward the data from one of the device connected on the I2C bus.
I2C devices/sensors can be daisy chained on the same bus. Each devices have an unique I2C address on the bus (7 bits address, value from 1 to 127).

{{asm-text}} Some of the GPIOs are attached to radio module.
As a consequence they are not available for use on the GPIO breakout.
