Quite happy to wait! I like that deep sleep function and never really thought about using it; But it seems like a great way for the device to call home on batteries or be an alert bluetooth beacon like an airtag.
Yup, the ESP32 is a very popular MCU for wireless projects that run off battery. For sensors and portable projects. Going into deep sleep (with a super low current) is very important for making your battery last as long as possible.
@@UnexpectedMaker Kevin Darrah is one bloke I've been following closely showing the true potential of these hooked up to a mobile phone network! The mesh capabilities just makes it so perfect for my own projects, hope others see the same!! Lady Ada also just made a video of it running Doom also!! Crazy times!!
Can it be programmed in circuitpython like any other feather from Adafruit? Or does it rely on the web-workflow (which I think the 8266s used)? Thanks!
Is it bad that I almost created an account on some random site just so that I could correct them that their Adafruit Feather S2 was really an UM Feather S2? Now that I've been spoiled, I think the only thing I could want added to the Tiny series of boards is a QWIIC/Stemma QT connector. And I have to say, you do a much better job of cleaning the fiberglass from your boards than some 'fairly' popular British companies do. Can't wait to add a few S3s to my collection. No need to wait for Arduino when I have some variant of python to work with.
Lots of Adafruit resellers list my boards as "Adafruit" boards because they come from Adafruit. I used to get annoyed, but not any more as it's out of my control ;) There's no room for a STEMMA connector on a TinyX board. But I did make this shield that gives you 2, and one of them has user controlled power. unexpectedmaker.com/shop/shield-i2c-breakout
So, a year later, i get round to using them as i need me memory for my project, i can not for the life of me get them to work, i have tried all sorts, they are recognised, by ide and win11 try to upload, error code then the com port drops out on the win device manager and then you press rst on board and port comes back...
Hi, really excited about this board. Can it be programmed in circuitpython like any other feather from Adafruit? Or does it rely on the web-workflow (which I think the 8266s used)? Thanks!
Do you have a good reference for a beginner? I’m hoping to get a better understanding of building a sensor array (for humidity and temperature), but I’m not sure where to start. Eventually I’d like to have a data logger in my house that gets data from the array (in my shed roof) using LoRa. But just getting the data from a sensor is what I’d like to understand first. I’m wondering if each sensor needs one of these.
I've been hanging out for these boards since i first heard about them last year. Glad to see you're making progress on them. Just one question, will these new boards have the ability to connect a JTAG / ESP-Prog device for code debugging? These debugging boards required GPIO 12,13,14,15 but the TinyPico devices didn't have GPIO 12 and 13 available as they were used on the APA102 LED.
Board specs and dimensions etc will be available very soon when the new website launches. No plans on making a slimmer version. If you ned something slimmer you can contract me to make you something custom.
Hey, seon.. I know it's little late to ask but I was wondering there is no UART bridge ic's like cp210x , can we program s3 with direct usb or what? do we need any bootloader or anything? any help or link related is appreciated. Thank you for such lovely s3 boards.
The board looks very neat. Great work. Just wondering, in your experience which antenna performs better SMD(which you used) or patch antenna/Pcb antenna? Your feedback will be appreciated.
PCB antenna will perform much worse - it's a 2d plane, so more susceptible to board orientation, and just less gain than a proper antenna, so less power. They are also considerably bigger, but they cost les ;)
@@UnexpectedMaker Thank you so much for your reply. So the antenna you used in FeatherS3 and Pros3 is more reliable than pcb antenna? We just want to get rid of large space occupied by pcb antenna in our design with SMD antenna you used in your products.
Very interesting video, thank you. Is it the PSRAM that's causing most of the deep sleep current draw or have you struggled to get decent LDO's and had to compromise? I ask as I've tried countless boards and settled on DFROBOT's FireBeetle V3 (an ESP32-WROOM-32D no PSRAM). It's deep sleep was the best at ~9uA measured on my Otti Arc. If it is he PSRAM would be nice to see a version without for a potential doubling in battery life. Would be nice to upgrade to the ESP32-S3 for some new projects :)
No it's not the PSRAM The PSRAM and Flash is shut down in deep sleep on all ESP32 boards. The ESP32-S3 current draw is totally different to the ESP32 - You can't compare them. No compromises on my LDO - I went with small package and massive headroom (700mA) which is way more important than saving 1-2uA.
@@UnexpectedMaker this may be a stupid question but why can't you compare the deep sleep current of the ESP32 and the ESPS3? In what way are the different? Which has the lowest power?
Using your distributed schematics, in feather s3 model you used 8mb psram what if i add same or another psram like parallel to the other, can it work like 16mb psram. I mean is it possible to use psram like ram in pc case? Should i manipulate the code, settings and libraries on arduino ide? Will they work?
No, you can't add to 2x PSRAM chips together with Arduino, and even in IDF land, you'd need to add the ability to have 2 chips yourself in a very very low level way - if even possible at all.
@UnexpectedMaker really thank you for your reply. I have one question more if you interest, can i use sram instead psram with the same codes, libraries with esp32s3 chip? I mean, i wanna design my own board using esp32s3 chip, in datasheet it is said that you can use up to 1gb of external ram. I need a ram that is more than 64(8*8mbit). I couldnt find psram more than that. Can u give me some advice?
@@hamidemin5690 you can only use external PSRam and can’t get it large. Why do you need so much RAM? It’s a microcontroller. If you need lots of ram use a computer like a raspberry pi.
Its been a blast seeing the portfolio grow and the boards improve. Great work
Are you suggesting there's something wrong with my previous boards???? hahaha, just kidding, Cheers!!!
Awww. Not even one glimpse of a laser in this vid. lol
Great work on the boards. ;)
Woooow! That are some amazing updates!!
Super cool, and that's some great low power current! That ppk2 is such a nice gadget.
Awesome work Seon!
Neat work. I’m looking forward to using the feather as soon as the chip deities allow.

Just picked a ProS3 from Adafruit! So excited to experiment with it and see if it will be a worthy fit for my project!
Can it be programmed in circuitpython like any other feather from Adafruit? Or does it rely on the web-workflow (which I think the 8266s used)? Thanks!
Great boards! I bought 2 of the featherS3 boards and am just wondering when the fritzing part will be released? Thanks so much.

Oh i also ought to add, the charge battery led, is blinking constantly ?
Love your work!
Great wotk Seon. Nice one.
Cheers Dave!

Full USB mass storage just like my ESP32-S2 boards, so the CP drive mounts on your computer and you load/save files like any other USB based board :)
Ooooo. Collect the set!
/me rushes out to design more variations... hahaha

Lot's of tutorials on YT and stacks of blog posts - Google starting with ESP32 and go from there?
Great work! But hey, what is lightsleep current like?! ;-D
Good morning,
where I can find the .bin file for your UM Feather S3 factory-reset-and-bootloader, Thanks

All 3 have USB Serial JTAG support, and the proS3 also has the JTAG pins broken out on the header :)
@@UnexpectedMaker Excellent - You legend!!
He didn't blink once during the intro😂
I did, but I cut those bits out as me blinking looks creepy? ;)
@@UnexpectedMaker ain't nobody got time for blinking
@Unexpected Maker what are the dimensions and can/would you make one extra slim version??
Board specs and dimensions etc will be available very soon when the new website launches. No plans on making a slimmer version. If you ned something slimmer you can contract me to make you something custom.
Could these boards be used with WLED for led strips and pixels RGBs, thanks
Eventually :) There's not Arduino support for them yet, and platformIO hasn't even got S2 support yet.

What is the power consumption like with the device running with BLE?
Hello nice work.
I’m struggling with the matching circuit.
May I ask how you did yours?
Thanks in advance.
A VNA, lots of measurements and patience.
@@UnexpectedMaker same here:)

finally!
What deep sleep current can I get with ESP32-S3 Feather board?
Approximately 30uA - It really depends on language you use, how you set wakekup an and what else is connected to the board :)
Hi, great job! When is it expected to have support for arduino ide?
I have no idea. That's a question for Espressif as they provide the ESP32 support for Arduino :)

Am rewiring to Poe for my installed boards. (ANDREAS SPIESs) BLOGGER HAS RED ONES. BUT NOT SURE THEY ARE (S3).
Do you have ESP32 s3 (poe)?
What is LDO ?
will the deep sleep work on the neo feather S2?
