Adafruit trinket 5v power draw6/1/2023 Also has headers for an FTDI port for reprogramming.USB bootloader with a nice LED indicator looks just like a USBtinyISP so you can program it with AVRdude and/or the Arduino IDE (with a few simple config modifications).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 5V regulator can provide 150mA output, not 800mA out.
