With this breadboard you will be able to perform your tests and experiments, having a complete and easy access to the pocketqube bus. A matrix of standard pitch connections (2.54 mm) will allow you to make your own experimental designs by placing new components.

On this PCB of your NessieSat, you will also find a sensitive light sensor (TEMT6000) that can be used as an Albedo sensor, connected to one of the analog inputs of the OBC (AD3).

In addition, you will find 3 LEDs of different colours, so you can use them as you like.ç

All connections to the PQ20 BUS are easily accessible to be wired to your own designs on the breadboard.

The NessieSAT EPS includes control signals, inputs and outputs that allow it to control external devices and new PCBs. In this BUS called PQ20N you can find the following lines.

• UART RX (high speed serial data input connection)

• UART TX (high speed output data input connection)

• D5 Programmable digital input / output

• D7 Programmable Digital Input / Output (for use in EPS in Alert Power Detection)

• D6 Programmable digital input / output

• +3V3 Rail voltage from EPS

• AD3 Analogue input 12 bit resolution (connected to Albedo Sensor)

• AD2 Analogue input 12 bit resolution

• AD1 Analogue input 12 bit resolution

• AD0 Analogue input 12 bit resolution

• DONE Interrupt input for indicating full battery charge

• IMU Interrupt input for IMU

• MISO High speed SPI BUS input

• CHG Input to indicate that the batteries are receiving power from the solar panels

• MOSI High speed SPI BUS output

• SCK SPI bus clock signal

• SDA I2C bus data signal

• SCL I2C bus clock signal

• GND Ground plane

• +5V Rail voltage
