A PCB.Nice. What is it?
Looks more to me like a drawing of a PCB. Not the same thing.A PCB.
Think I see a bug, that is error. Can you find it?
Exactly.Looks to me like one of those things you use to hook to one of those other things so that the two things can work together. Am I right? Probably not. But what do I know?!
Exactly, what? "It hooks one of those things to one of those things"? Or "What do I know"?Exactly.
Interrrrrrresting... I see an LCD on top, and a few pushbuttons on the bottom, and it looks like you're using only two layers, with no ground nor power layers... what software did you use to draw it?
Yup.Exactly, what? "It hooks one of those things to one of those things"? Or "What do I know"?
https://forum.allaboutcircuits.com/threads/microchip-rn4020-bluetooth-le.105531/U302 has an interesting footprint/decal. What is it?
Ground and power planes are overrated.with no ground nor power layers
Right now I'm working on a design that will require the use of bluetooth, but not necessarily ultra low power, since it will be installed in distribution trucks for the gas industry. I was thinking about using the hc-05 or hc-06 modules for that effect. But they seem to be too inexpensive and too easy to use for me to believe that they're the top technology out there.
The HC-05 and -06 are SPP (serial port protocol). RN4020 is straight BLE (Bluetooth Low Energy)Right now I'm working on a design that will require the use of bluetooth, but not necessarily ultra low power, since it will be installed in distribution trucks for the gas industry.

Other than the low power promised by the RN4020, what other advantages does it have? Speed? Range? Reliability?
Thanks for the warning. I'll stay away from that module until a very low power is demanded from my projects... and when that happens, I'll know exactly who to ask for help from...The HC-05 and -06 are SPP (serial port protocol). RN4020 is straight BLE (Bluetooth Low Energy)
Aside from that, there are absolutely no advantages to using RN4020. It's a bear of a part to program for (as my thread attests).
I neglected to answer this question. Sorry. Better late than never, I guess....what software did you use to draw it?
Gorgeous work ... I'm betting that 99% of those traces are digital, right?Here's a portion of another one I put together over the last two days. It's amazing what one can do with two layers when one puts his mind to it.
This time, it's a screen shot of the Gerbers as viewed on gerbv.
