Arduino pro mini adafruit3/1/2024 On-board 3.3V power regulator with 150mA output capability and ultra-low dropout.Micro-USB jack for power and/or USB uploading, you can put it in a box or tape it up and use any USB cable for when you want to reprogram.Also has headers for an FTDI port for reprogramming.USB bootloader with a nice LED indicator looks just like an USBtinyISP so you can program it with AVRdude and/or the Arduino IDE (with a few simple config modifications).ATmega328P onboad chip in QFN package running at 3.3V logic.The bootloader does not affect RAM usage. The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is 28,672 bytes.The USB connection is for uploading new code only. This is to keep the Pro Trinket small and inexpensive, you can use any FTDI cable to connect to the FTDI port for a Serial connection. There is no Serial-to-USB chip onboard.You cannot plug shields directly into the Pro Trinket.The onboard power supply is a 3.3V regulator and it can provide 150mA output.Only the most timing-specific libraries may be affected, check the documentation! The NeoPixel Library works fine at 12MHz. The Pro Trinket 3V runs at 12MHz, this doesn't affect most projects. ![]()
