Necessary info about the PCB, pinout, and markings is currently not in the OP. "Arduino Pro Micro Atmega32u4 5V/16MHz" and adding the Rosetta Stone pic would convey that info. Scott |

Scott --- End quote --- @PL1 therefore Pro Micro and Itsy Bitsy 32u4 is the same board but with only different pinouts? thanks |

I do believe you won't need anything specific, except for the wavelength, as mentioned earlier. I run mine at the lowest voltage that is specified and works at 3 meters distance. I bet I could go even lower ;D |

If you look at the ItsyBitsy or Pro Micro schematics, the two main components are an ATMega32u4 processor and a 16 MHz crystal oscillator, both running on 5v. - The supporting components are a few capacitors, resistors, LEDs, a USB connector, a reset switch (ItsyBitsy), a fuse (Pro Micro), a Zener diode, and a power regulation chip. The other possible difference between boards is the bootloader. - It determines which program (AVRDude, FLIP, etc.) you can use to load the firmware into the 32u4, but it won't matter once the firmware is running. The various 32u4 boards aren't exactly the same, but the firmware can't tell the difference. - As long as the board fits into your gun shell and you connect the various inputs/outputs correctly, it should work. ;D Scott |
