nano 33 BLE problems with reading RC signal

I'm using an Arduino Nano 33 BLE and a L293D motor driver to control a three-wheeled RC robot. The sketch I'm using worked fine with my Uno Rev3, but I've moved to the Nano for size/weight reasons, and it's no longer working. Whenever I turn the…

Nano 33 BLE Sense powered with Vin and USB at the same time

I have a project where I would like to power an Arduino Nano 33 BLE Sense with USB and Vin at the same time. The idea is to charge an external LiPo 3.7V through a charger module that would take the load from the 3.3V pin (that would be powered…

RFM69HCW connected to Arduino Nano 33 BLE

I tried to connect my RFM69HCW to Arduino Nano 33 BLE, so that I won't be needing a logic level shifter to downgrade the voltage, since Arduino Nano is already 3.3V. Upon checking its data sheet and pinout, I noticed there's no dedicated pin for CS…
