      I smell a rat here. When he's filming outside and showing wifi activity in the carpark, there's zero wifi activity from the building behind the carpark. That building appears to be apartments or offices, there should be multiple access points showing up.

    Pretty rough pricing as these are roughly $4.50 ex-gst on Ali when you (ab)use bundle deals and free shipping.

    • AssociatedZaitronics @ Zaitronics on 18/02/2025 - 21:04

      We honestly don't even receive them for that cheap. Those bundle deals are usually once off or the price changes when you log in.

    • RedHab on 19/02/2025 - 11:48

      This is ESP32-S3

      My experience with Ali is that even if they claim to be -S3 and may even say so on the chip there's a good chance it's the much slower original ESP32. So you might get lucky and get what is on the listing, otherwise you might not.

        They certainly look like ESP32 S3 N16R8 boards and are advertised as such, but as I and the Zaitronics rep have mentioned, said pricing depends on using the "Pick 3" promotions, which may not be reliable to get.

        Normal pricing without welcome or the specific "pick 3" promo I saw appears to be ~$7.25, which is much closer to what the Zaitronics rep is offering.

      We'll be adding more boards in the near future, but are currently focusing on moving locations.

    How do these compare to pi Pico?
    Can i code micro python or similar?
    Are they similar power?

    • Corapmafya on 19/02/2025 - 10:17

      You can code using micropython on esp32 dev kits but it will use more processing resources compared to Arduino code. Depends on your application whether this will be noticeable however.

  • deeevan on 18/02/2025 - 22:09

    Thank you for reminding me I still haven't done anything with my S3. I want to see if it can replace my pi-hole

    • noisymime on 19/02/2025 - 12:15

      For the love of god, I wouldn't recommend it. The wifi speeds of these C3 and S3 units really aren't great, your DNS resolve times are going to be pretty high.

      This is the diy tinkering version of the motherboard that has the same kind of chip that lives in lots of smarthome wifi devices. Obviously not the exact same chip, and not with the same software. Will require diy programming or copy/paste/upload of code from online to get it to be useful. Example uses include: wire up to led lightstrip, and control from your phone. Or, wire up to your home aircon to maintain temp, and control from your phone.

    • Russ on 19/02/2025 - 13:13

      A raspberry Pi is faster, has way more memory, and more peripherals (like a wired ethernet connector and a USB3 interface). Raspberry Pi can run a multi-tasking operating system, the ESP32 can only run one fixed task. It's like Windows versus MS-DOS.

      But the raspberry Pi is much larger, more expensive, uses more power, and runs a lot hotter, so ventilation and/or cooling is often required.

      • AssociatedZaitronics @ Zaitronics on 19/02/2025 - 13:17

        Depends which Raspberry Pi. I think they were referring to the picos, which is much more comparable.

    Can you provide some useful examples of use for the ESP32?

    with its dual USB-C ports

    OP, it would help if the specs say what speed the USB is, so we know if we can, for instance, connect a webcam and get live video. If it's USB1 at 12Mbps, that's a bit too slow for hi-res video.

    It'd be a cheap way to roll-your-own video doorbell if the USB is 480Mbps.

      • Russ on 19/02/2025 - 12:28

        Excellent! All the work is done for me!

      Not explicitly stated on their website, but the same boards on AliExpress are USB2.

        Correct USB 2.0.

        • Russ on 19/02/2025 - 12:14

          Correct USB 2.0.

          That doesn't give the speed. There are two "speeds" of USB 2.0:

          • "USB 2.0 full-speed" is 12Mbps, same as USB 1 and USB 1.1
          • "USB 2.0 high-speed" is 480Mbps

          The USB foundation made this shonky definition when manufacturers complained, so the manufacturers could continue to sell USB 1 devices with a "USB 2.0" label stuck on the front of their packaging.

        • Russ on 19/02/2025 - 13:19

          Correct USB 2.0.

          The manufacturer says USB 1.1:

      • Russ on 19/02/2025 - 12:12
        +1

        I found the info on the manufacturer's website, it says "ESP32-S3 full-speed USB OTG interface, compliant with the USB 1.1 specification". The manufacturer does not claim USB 2.

        "Full-speed" means 12Mbps, which is USB 1 speed.

        480Mbps USB is called "High-speed USB 2.0". Any sellers just saying "USB 2" without saying "high speed" or "480Mbps" are usually trying to deceive you. See my comment above for a longer explanation.

        Here's where I found the info: https://docs.espressif.com/projects/esp-dev-kits/en/latest/e…

  • skegger on 19/02/2025 - 09:36

    I grabbed one. I've been tinkering with older devboards lately just for the heck of it.

    Looking for one that has an inbuilt battery charging circuit? bonus if has JST connector on board

    • AssociatedZaitronics @ Zaitronics on 19/02/2025 - 11:57

      We do have a few ESP32 boards with the jst-ph connection, but haven't added it to the website yet. Email us if you're interested.

    How do you get the $3 delivery

    • AssociatedZaitronics @ Zaitronics on 19/02/2025 - 11:56

      Orders below $15 in value get the $3 untracked letter delivery option. It is still not recommended as letters can occasionally go missing.

      • bigbargainsmall on 19/02/2025 - 12:30

        oh okay, all good. i bought everything you recommended and an LCD display. cheers
