I’ve been trying to use the 5V Adafruit miniboost in a project. I have a cheap 433 Mhz reciever which needs at least 5V. I noticed that I get really poor signal when using the miniboost. The miniboost always gives a little bit less than 5V, 4.96V Ardunio Uno and 4.84V Arduino Nano IoT 33. I’m connecting the miniboost to Vin.
Using the 5V out on the arduinos gives really good range for the receiver but eventually I want to switch the Arduino for a processor which doesn’t have 5V out.
Am I doing something wrong or is this a limitation of these miniboosts?
