HackSat One Sprite Hardware
HackSat One is a tiny self-contained satellite sprite. The hardware design is set as part of the KickSat project. It consists of a 35 x 35 mm circuit board with an MSP430 microcontroller, solar panel, magnetometer, gyroscope, oscillator and dual antennas. The board weighs about 5 grams. For details of radio reception hardware, see ground station.
Components
Below, you can see a photograph of the dev board and dev kit. The sprite board itself is outlined in yellow, with the solar panel taking up most of the left-hand side. The boards beneath beneath the sprite are the TI LaunchPad and connecting board. Key components on the spite are:
- TI CC430F6137 microcontroller: 16-Bit MSP430, 32KB Flash, 4KB RAM, CC1101 Radio [datasheet]
- InvenSense ITG-3200 Gyroscope [datasheet]
- Honeywell HMC5883L Magnetometer [datasheet]
- TXC 7Z-26.000MDG-T Oscillator [datasheet]
- Nitinol antennas (extend off top right of photograph) [nitinol info]
For more detail on the sprite hardware, including EagleCAD layouts, see the KickSat Git repo.
NB. The dev board (pictured) has a different oscillator to that mentioned above.
