#Adafruit trinket 5v vs 3.3v code#
The code I am using works fine with an Arduino Uno (same number of values coming in, but with a range going from 95 to 1000) while the Trinket ranges from 173-184ish. The data is being sent from a spectrometer. Attiny85 on-board, 8K of flash, 512 byte of SRAM, 512 bytes of EEPROM USB bootloader with LED indicator Mini-USB jack 3.3V or 5.0V power regulator with. On a 5V Trinket, the GPIO are 5V output level, and can be used with 3V.
#Adafruit trinket 5v vs 3.3v pro#
On a 5V Pro Trinket, the GPIO are 5V output level, and can be used with 3V inputs but may damage electronic devices that are 3V input only Aref pin - this is the optional analog reference pin for the analog converter, to be used when you want the top. All have built-in USB and are comparable in price The ItsyBitsys especially are about the same size and have native USB and tons of pins, so theyre a very close compatible.Trinkets got a big sister in town. On a 3V Pro Trinket, the GPIO are 3.3V output level, and should not be used with 5V inputs. Both work the same, but have different operating logic voltages. I'm noticing my data is not changing with an Arduino Pro Trinket. On a 3V Trinket, the GPIO are 3.3V output level, and should not be used with 5V inputs. Please check out the Metro Mini (ATmega328 5V 16 MHz), ItsyBitsy 32u4 5V 16MHz, ItsyBitsy 32u4 3.3V 8MHz or ItsyBitsy M0 3V 48MHz.
