Adafruit Microcontroller
Hello, I'm working on a project that requires the following hardware, microcontroller, datalogger (microSD card) and BNO055 which will interface with Arduino IDE, any suggestions on which Adafruit products to order? I'd need the equivalent processing power as a Teensy 3.6. Thank you

Re: Adafruit Microcontroller
A few questions:
- What do you mean by "interface with Arduino IDE"? (I assume you mean you are programming it in C++)
- Why the same processing power as the Teensy 3.6?
- What do you mean by processing power in this case? clock speed, flash, ram, I/O...
- How will it be powered?
- If you are data logging, do you want an RTC as well?

Re: Adafruit Microcontroller
Correct Dave,I’ll be using C++ to program it. Similar in terms of clock speed, flash and ram and it will be powered with a LiPo battery. Not sure what RTC is?

Re: Adafruit Microcontroller
SAMD51 boards are similar in processing power to teensy 3x
https://www.adafruit.com/product/3800 or https://www.adafruit.com/product/3857 (Digikey has some in stock)

Re: Adafruit Microcontroller
Do either of these two boards have a datalog option and/or any know issues working with a BNO055?

Re: Adafruit Microcontroller
If you choose the Feather M4 Express https://www.adafruit.com/product/2922 you can use the Adalogger Featherwing https://www.adafruit.com/product/2922 to give you a microSD slot and RTC. RTC (real time clock) is a battery backed up clock chip that keeps accurate time (once set) that you can use to timestamp log entries.
Both those linked boards (ItsyBitsy and Feather) work great with the BNO055.
