Is this feasible? Should I use a different microcontroller?
Hi all,
I would like to tip my toe into making a proof of concept and would appreciate guidance and advice.
I want to make a data logger to go on a drone that collects data from three instruments: GPS, inertial measurement unit (IMU) and a range finder.
For GPS, I found the Gravity chip
For the IMU, the Bosch BN0055 breakout board by adafruit seems great.
For the range finder, the Wasp 200 seems good. I just need a board to increase voltage from 3.3V to 5V.
For the microcontroller, I found the adafruit Pico 2024 feather board with integrated SD Card. I like the idea of logging to the SD card for simplicity. I want to log at 10 Hz with a stretch goal (for the instruments that can support it) of 100 Hz.
The Pico chip seems to have enough I/O to have a dedicated connection for each instrument. However, I’m not sure if this is the best and easiest microcontroller to use for this.
As far as I can tell, I should be able to wire up the board like this. Any feedback appreciated.
Thank you
