This board provides a six pin connector comprising the first six GPIO pins (including 5V, 3.3V, Gnd, SDA, SCL), and two 10 pin connections to the lower board, which includes: the outputs from the bumpers (BP, BC and BS); infrared sensors (IRP, IRC and IRS); motor encoders (A1, A2, B1 and B2); indicator LED; and bypass/switched 5 volt sensor supply.
Mounted on the chassis, an [Adafruit Perma Proto Bonnet|https://www.adafruit.com/product/3203] serves to collect the various power and sensor connections into three connectors: one six pin connector comprising the first six GPIO pins (including 5V, 3.3V, Ground, SDA and SCL), and two ten (2x5) pin connectors. These are commonly called ''Dupont Connectors'', bespoke cables made using dual row wire housings (see [Small Dual Row Wire Housing Pack for DIY Jumper Cables|https://www.adafruit.com/product/3143]).

The KR01 has a Perma-Proto board dedicated to holding an [ItsyBitsy M4 Express] and a [BNO055 9-Axis Absolute Orientation|BNO055-9AxisAbsoluteOrientationSensor] sensor. The various connections to and from the daughterboard are shown in the above photo. The two columns of cyan and magenta-coloured pins are used to explode the 5V supply, which are used for the bumper and infrared sensors.
Earlier I'd experimented using a Perma-Proto board dedicated to holding an [ItsyBitsy M4 Express] and a [BNO055 9-Axis Absolute Orientation|BNO055ImuSensor] sensor. The various connections to and from the daughterboard are shown in the above photo. The two columns of cyan and magenta-coloured pins are used to explode the 5V supply, which are used for the bumper and infrared sensors.

This board is currently not functional. The BNO055 is incompatible with the Raspberry Pi, so the ItsyBitsy will be used to drive the BNO055 (and potentially poll other sensors).
This board is currently not functional. The BNO055 is theoretically incompatible with the Raspberry Pi (the I2C bus speed needs to be slowed), so the ItsyBitsy was used to drive the BNO055 (and potentially poll other sensors). It seems the BNO055 is working okay with the Pi so lately I've just been connecting it directly.
