RF Transceiver
About
This project enables RF communication between two STM32F302 MCUs over the 460 MHz band. It includes two analog peripherals, a potentiometer and a temperature sensor, so there is data available to transmit during testing.
The aim of the project is to get the designer familiar with RF PCB design.
The system will be used to command the Attitude Determination and Control System (ADCS) from the base station (computer application). The RF and ADCS systems will communicate over UART which has been exposed on the header pins of the PCB.
When the systems are connected, 5V power will be supplied via the ADCS, and can be selected with a jumper on the board. The two systems will communicate over USART, which has been exposed on pin headers.
Primary Components
| Part Number | Description |
|---|---|
| STM32F302 | Microcontroller |
| ADF7030 | RF Transceiver |
| BGS12WN6 | RF Switch |
| ADP5310 | 3.3 V Buck Converter |
Status and Next Steps
Currently the PCBA is being manufactured by JLCPCB. In the meantime, the software is being written for the transceiver to test communication.
Once this and the ADCS are complete, integration with that system will begin.
