Thank you soo much for the advice, I will consider the options and do accordingly

AOhh great.
TWhere are you located, maybe I can set you up somewhere as an unpaid training and later to convert to paid in startups
TIn Bangalore
TOkay, I am sure there are many startups working is similar domain who would love to give you a start, do ask for incentive-based work
TYes, I will approach them in LinkedIn, thank you so much for the advice
P@kmulier Would it be possible to start a separate room/chat for the Scarab board? Here in the dev-chat there is a mess. I almost don't read the messages here. To your question. I recommend considering the 0402L020SL or even 010SL. I recommend to consider the average power consumption of the board and make a decision based on that value.
THey hey, thanks for the suggestion, tahenan. We actually have restream capability in our platform so we plan on starting the external stream to LinkedIn, X, YouTube, insta, etc., as soon as we finish the configuration. Should be within a couple of weeks.
TI actually asked if we should start another forum or chat channel for the Embeetle/DevHeads TinyScarab community development platform (featuring WCH RISC-V microcontroller and later RP2040). What do you think, guys?

NYeah so much so. And this is of course not dev-chat. This is turning to be a welcome chat with mix of everything.
One thing to do is kick the DevHeads bot which keeps screaming about verification of new people to another space named #intro

NI think there was one channel like that - doesn't seem to exist.

Noh boiii. Just looked at their catalogue. Some awesomazing products. I am liking this one https://www.wch-ic.com/products/CH32V208.html?
not easy to get all this features in a package - perfect IoT MCU(has ethernet PHY and MAC within! gateway applications). Unsung hero of IoT MCU.

FEh I think it lacks some tool chains and tutorials right at the moment. That is making it harder for newer people to get into it. But expert like you guys should have no problem haha
Byep I agree there
TThanks for the feedback. We'll look into bringing an intro/welcome channel back for the first time.
UHi @fwen agree with you. Sometimes even experienced people concerned about new tools especially unpopular ones. It leads to time investment and not getting the expected results causing delays in project delivery.
K@Navadeep , @fwen and @Umesh Lokhande ,
You guys said about the WCH chips:
We're solving that with Embeetle IDE [see https://embeetle.com] - not only for WCH chips of course, but for all the MCUs we integrate, we're not bound to a specific vendor. Here's what Embeetle can mean for you when you want to get started with a new MCU:

- Embeetle provides one or more sample projects for your MCU, typically to blink an LED for a quick start.
- Embeetle downloads all the tools automatically when you launch a project (compiler, flashtool, ...).
- Embeetle provides excellent documentation on the MCU and the dev board, eg: https://embeetle.com/#supported-hardware/wch/boards/ch32v003f4p6-evt-r0-1v1
KSorry for the shameless self promotion 
KAnyway, Embeetle is free software.
FI'll make sure to check it out if I get my hand on a WCH microcontroller.
KI can send you the Tiny Scarab board when it's finished and fully tested. I might have to ask a little compensation for the production costs. I'll share more on that later here in the chat (once I have a definitive production cost estimation).
Fthanks!!

THey @everyone, we're starting in a couple minutes! See you in the meetup!
DCongrats @ygramoel ! You've been Verified!
S@ygramoel Welcome! will be happy to know your technical background and what project you're working on these days.
N@everyone Thanks for tuning in for today's DevHeads Office Hours! We talked all around IoT FOTA, Tiny Scarab board and about some exciting demo videos coming up. Again, cheers to all new Dev's!
People who have missed this can always watch the recording. Stay tuned and keep smashing that bug.

YHi @Saßì , I'm currently working on the Embeetle IDE together with @kmulier, I have a background in EDA tool development mostly, also all kinds of electronics project, started working in 1983, long before internet became ubiquitous. Trying to figure out what devheads is all about
YTo be honest, I don't really understand how Discord works yet. Typing this on my phone because haven't figured out yet how to connect to this channel on my pc
NYThat worked, thanks
PI got my hands dirty on Resin 3D printing for the very first, Results are flabbergasting.
A word of caution for those who wanna try the same:
This model took 3 hrs to print, 30mins of post processing and almost 2.5-3hrs to clean all the mess

SHello guys,
I wanted to know more about standardised architecture of linux based embedded system.
My system is having Digital IOs, Analog IOs, CAN, Modbus over RS485, RTC, Web server etc....
Hardware is ready. Also, it's working smoothly but i dont want it to be tightly coupled.
What i want is every other module will work independently and i will code the application (Custom logic) only as per requirement.
Any suggestions, posts, links.....i am relatively new to this.
Thank you...!!

Aas the requirement you have provided ... i feel that all these input interrupts and outputs should have thier own logic and so some kind of ipc ... in that situation you can utilize some ipc methods or else you may use ros as an architect ... where everything is a pub sub structure and considered as nodes ...
Aalso may i know the environment and mpu details ..
Abuild environment*
Ahere by ipc i mean ... inter procedure communication ...

KI'm placing TVS diodes at all the IO pins
KFor example:
K
KI also installed plenty of 'security' at the USB port:
K
K(1) TVS DATA LINES
TVS Diodes protect the USB data lines against voltage transients.
(2) TVS 5V POWER
A larger TVS diode is placed on the 5V power incoming from the USB connector to deflect voltage transients.
(3) ZENER 5V + (4) FUSE
A zener diode of 5V6 (I took a bit of margin) is connected to the 5V USB power line. A permanent overvoltage will short through this zener diode and burn the fuse. The rest of the circuit should be fine.
(5) PMIC 500mA
A chip lets only 500mA pass through from the incoming USB power to the rest of the board. In case of overcurrent it will shut down and lit the LED.

FThat sounds wayyyy overkill for such a cheap microcontroller
FLike for me personally I think replacing the microcontroller itself would be cheaper
T@Wired & Wireless Networking folks, any suggestions on the best MQTT client software to use when testing MQTT topics during development? At least as far as ease of use and security are concerned..?
Amqtt explorer is what i prefer for the ease of usage
TNice! Thanks. I'm looking into it. Looks like it checks a lot of boxes around open source, platform support, and decent enough documentation, BUT...
Is it still being maintained?
