It would be helpful if your site had KiCad symbol and footprint for the CodeCell and an easy to read pinout. Same for all of the other items too. Thanks
I just saw a vid where someone connected a NANO to a digital caliper through i2c. It used 1.5v logic.. Would your CodeCell be able to do that and post data to MySQL?
As someone who designs and measures antennas, the problem is not that the cable is shielded or not. The problem is that those antennas are designed while assuming that underneath them is free space, if you introduce an object (obviously metallic objects are worse) in the antenna's near-field, you change it's S11 (reflection coefficient) and radiation pattern, and it's efficiency *MIGHT* drop, since more power is reflected back to the source. I say might because the response is actually unpredictable, even I designing antennas for a living don't exactly know what might happen when certain objects are placed. RF is black magic after all. However, as you tested, the antenna seems to be responding quite well to the USB-C cable so... fair game! Good job though!
Would it still be a problem when the cable isn't plugged in, just because of the socket? Because otherwise, it seems pretty reasonable to not use wireless _while_ it is plugged into USB.
ESP32C3 Seeed studio's wifi & bluetooth will work without external antenna. i used it my smart watch showing internet ntp clock without antenna. please check that once without antenna it has good connections. i dont know how its work without antenna but its working.
Hey Carl. Im the same Seth that hit you up a while ago about using drivecells in my small robotics project. Thanks for responding and talking with me. The new drive cell library is much better.
I wish you could've squeezed some motor drivers or just mosfets on there for direct motor drive. (4 mosfets and you would've had yourself a mini drone!)
The XIAO ESP32C6 is the same size as the C3 and has an internal antenna in addition to a connection for an external one. And it has zigbee, which could be convenient for power usage.
You should really put in your video that you can save up to 45$ in shipping by not adding on the battery. I took it off and it dropped the price from 90$ to 40$ which turns the product from kind of stressing pricing to actually very reasonable for a research device. If I buy a lipo locally on amazon I can get like 20 of them for that markup.
So much features in this tiny volume, you did a really nice job Carl ! Even took the time to do a pretty nice animation for the intro ! What did you used ? Blender ?
This immediately remind me of SlimeVR trackers. Will you sell units with wiring & solder points for IMU but without the actual IMU？coz I have a bunch of BNO around 😄. I can solder them myself. This tiny C3 board should be ideal for assembly of super tiny SlimeVR trackers！😉 Pls consider selling ESP-C6 ver too. Having 2.4GHz ax channel can be helpful sometimes. Thanks.
