| **System Block** | **Hardware Chosen and Reasons Why** |
|
|
| :--- | :--- |
|
|
| Buck Boost Converter | TPS63070 <br/>We chose this part because of oresat heritage. This component is being used elsewhere in oresat and we were recommended to use it. It is a buck-boost converter that can take a wide range of input voltage. Overall, it is a robust component. |
|
|
| BLDC Motor | MakerFire D1104 7500KV <br/>This motor was chosen for its operating range and torque output. <br/>The motor selection should be reevaluated if it is decided to move to a 7.4V nominal battery bank voltage |
|
|
| BLDC Motor Driver | STSPIN 230 <br/>We chose this component for a number of reasons. Namely; <br/> - Satisfies thermal and voltage constraints. <br/> - Small form-factor. <br/> - Half-H-Bridge control over each phase of the BLDC. <br/> - Easy interface with STM32F0. <br/> - Full Control over Phase Output. <br/> - Minimal External Components. |
|
|
| Encoder | AS5047P <br/>The AS5047P utilizes an array of Hall effect sensors and a diametric magnet to provide a precise position reading. The sensor provides sufficient precision and provides output data in multiple convenient forms. See the datasheet for details. |
|
|
| MCU F0 | STM32F042K6 <br/>We chose this MCU because of oresat heritage. It is being used elsewhere in oresat. This MCU has a small form factor and is power efficient. |
|
|
| CAN Transceiver | TCAN330 <br/>We were told to use this component because of oresat design heritage. The rest of oresat is using this CAN transceiver. |
|
|
| Brushed DC Motor Driver | STSPIN250 <br/> We chose this component for a number of reasons. Namely: <br/> - Satisfy thermal and voltage constraints <br/> - Small package size <br/> - Full H-Bridge control <br/> - Basic Magnitude and Phase control <br/> - Minimal External Components |
|
|
| Magnetorquer | Still to be determined. <br/> The magnetorquer will essentially be an inductor most likely in a flat spiral orientation to save volume inside oresat. |
