3/24/2024 0 Comments Adafruit trinket 3vThanks so much in advance for any advice. In the IDE the adafruit package only contains the Trinket 5V, which I select for compiling and uploading the sketch, this cannot have something to do with it right? So this shouldnt be a problem in the first place. Maximum current I measured was around 100 mA, as expected from the datasheet. I measured the voltage of the Adafruit trinket outputs to be close to the expected 5V. The displayed current never goes above 8mA. If I use an external 5V power supply to simulate the signal output (istead of the trinket), everything in the circuit works fine. I'm powering the trinket via an external 12V, 3A power supply connected to the "Battery" Pin. They are almost identical but there are slight differences in the pinouts: one has a 3V output pin in the bottom right, the other has a 5V output pin instead. There are two versions of the Trinket: 3V and 5V. In fact, the Relais does not work anymore at all and the LEDs are much darker, just barely noticable. Pinouts Introducing Trinket Adafruit Learning System. However, it uses 3V logic and 12MHz clock which means it's good when you want a lower-power and lower-voltage setup. I just want to control a Relais and some status LEDs.Īnd yet it seems like the digital out signals do not supply enough power to run the circuit properly. Adafruit Pro Trinket - 3V 12MHz uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. I'm having trouble shrinking a project of mine from Arduino Uno to an Adafruit Pro Trinket 12V.
