    if your going from AVR to Pi or STM32, remember your i/o is 3.3v
    good for displays - you dont need resistors,zeners or buffers anymore - but may need a bit of attention with some sensors

      I've had two Arduino Due's ... and managed to foul them up pretty nicely because i wasn't being mindful of the 3v limit. However, these Teensy 4.0's I've managed to not damage and they are 3v so ... this old dog can learn some new tricks.

        Are Microchip/General Instruments PIC8s dead yet?
        If so, good riddance.
        If not, ()#$*#(@#*(@ their memory management.

          Could you have meant the PIC18 Microcontroller?

            No, I generalized all PIC 8-bit microcontrollers into the same bin... the trash bin...

              That's where my Commodore 64 went several decades ago and I still don't regret it ... even if these weirdos are obsessed with the C=64 making a come back... I don't live for the past ... I'm happy to be done with it.

                Never used a C64 but as a 6502 I don't think that's horribly bad. I do have my qualms with 6502 however, not a great processor either but much better than PIC 8-bit...

                6502s are fast however. Beats the Z80 which I've preferred, but 6502s murder the Z80 MHz for MHz.

                  This new laptop I got has 32 gigs of RAM in it...

                  My first computer, the C=64 had 64k of ram...

                  So TODAY, my computer has 500,000 times more ram than my first one.

                  That's pretty phenomenal to me.

                    Good night,
                    I am going to ask your help to find out what is the reference of this smd transistor. Or what is an equivalent transistor?

                    by danielgerman681
                    Hi, Im trying to find the area on the chip that contains all of my laptops information, but I havent found it. The laptop won't turn on anymore. I was updating the BIOS, and it was supposed to reboot itself, but it wouldnt turn back on. I ve tried every possible solution, every alternative on Lenovo forums, everywhere; I ve taken it to technicians, and no one has been able to fix it. I've already read the chip that contains the BIOS (Winbond 25Q128JSVQ) and searched for my laptops data, but they're nowhere to be found. I only find scribbles and lines of text indicating errors. Has anyone had a...

                    Garage door RX unit (Cardin S38C) does not short relay to send opening signal
                    by CoinCoin88
                    Hello everyone,

                    I'm turning to the Badcaps community to help me troubleshoot the radio Rx card from my (old) garage door opener. While I could just ditch that card and replace the whole system, I first would like to understand "why" it suddenly stopped working, because that's just how I am wired...!

                    Some basics: the receiver works on a 30.875 Mhz frequency. Yes, I'm aware this is not in use anymore in a looot of places. It does not use any rolling code, it's just a regular dip-switch code that you have to set up on both the receiver and transmitter. The receiver...

                    Where to find a very small fpc connector 0.3mm between 2 pins ?
                    by corrize
                    Hello, I search this connector (oxydated).
                    It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
                    I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
                    I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?


                    Do you know how to find this connector please ? What is the exact name for find it ?
