Automotive Telemetry board for data collection during testing. Logs vibration, pressure, acceleration and temperatures. Started this project to use while testing Paradigm and Formula MUN vehicles.

Targets were to have a PCB with an overall footprint below 50mm x 50mm, with mounting holes. Overall BOM price target was below $60 CAD. This was achieved through careful IC selection and reduction of unique parts.

• Uses SPI and I2C to log data from onboard Pressure Sensor & Accelerometer
• Logs position using U-Blox MAX M10-S over I2C. This was selected due to integrated LNA, SAW and low price
• Powered over USB-C 5V. Intended to allow connectivity and testing from any PC, as well as be powered using common power banks
• Onboard TI TPS62160DSG buck converter to convert 5V to 3V3
• Onboard Diodes Inc. AP2112 LDO to convert 3V3 to 1v8 to power BMP585
• Power indication LEDs for all power stages (using FET for 1V8 given 2V forward drop of LED)
• Thermistor linearization circuit to allow for easy modification of temperature resolution for varied testing scenarios

Rev2 Modifications vs Rev1

• Changed STM pin selection for simplified routing
• Changed from standard 20 pin SWD header to 6 pin debug header to connect to NUCLEO-F446RE CN4
• Switched from USB-PD only to USB 2.0
• Added MicroSD card slot to log data over SPI from the STM, allowing for data to be easily accessed and read on a PC
• Modified thermistor circuit layout to allow for easy modification & smaller overall footprint
• Decreased overall size of board

Potential Additions:

• Support for onboard battery (either 1S or 2S). This would require a power path management IC
• Potentially turn telem PCB into a TX module and develop an RX PCB to allow live wireless data logging

Custom flight controller PCB built for a 249g drone. The drone is intended to be used while hiking to capture images. The chosen camera is a RunCam Thumb 2. Board will be powered from a 2S battery, and will power and control four 10000KV motors.

• Controls four onboard motors using TI MCF8316A drivers over UART
• Controlling RunCam Thumb V2 Action Camera over UART
• Onboard accelerometer and pressure for positional data, using SPI and I2C, respectively
• Onboard BMS to protect 2S battery
• Buck converters to convert battery voltage to 5V & 3V3
• LDO to convert 5V to 1v8 to power pressure sensor
• SWD header to program and debug MCU using STM NUCLEO-F446RE Dev Board

Coming Soon:

• Adding RC receiver
• Potentially switching LDO for 1V8 stage to buck
• Adding charge controller to charge 2S battery over USB-C

250V Drivetrain and shutoff circuit for a full size FSAE EV

• Utilizing prebuilt 1S6P Molicel 35A modules to reduce labour needed for assembly
• Using 250V nominal to reduce cost for first year car, also reducing battery size
• Integrating Orion O2 BMS for 250V, 6 module pack
