Python is slower and has limitations, but you might find developing for it much faster. C / Arduino let's you exploit your ESP32 to the max, and there are some libraries that can't be found in micropython. However you might find it more tedious and messy. In my experience, if I don't care about speed (I usually don't), I use micropython.
Looks like your issue was solved, but I just want to put this out here for everyone. This reference may be helpful for setting up an MCU-driven LED circuit.. It covers a lot of the best practices (logic level shifting, capacitors for smoothing transients coming from the power supply, resistors at data output pins for stability, etc.).

The manual provides detailed and complete information on how to use the ESP32 memory and peripherals. For pin definition, electrical characteristics, and package information, please see ESP32Datasheet. Document UpdatesI'm currently split between getting an Arduino or an ESP32 mainly for learning and no particular project in mind. Get both! Arduino Nanos are cheap, good for "throw away" …Easy threading on the ESP32. It's really difficult to chase down race conditions, even with a debugger. Because of that, you may hesitate to use the secondary core on applicable ESP32s. I've created a PlatformIO library to make it almost foolproof to write code that targets the secondary core or just a secondary thread on the primary core.Get Any Reddit Post using ESP32 Roland Pelayo November 30, 20216 mins read Reddit's API has been piquing my curiosity for some time. However, my past experiences with APIs, especially with Twitter and Facebook have left a bad taste in my mouth. Then one day I had the courage to try it again and to my surprise, it's far easier than it looks!The ESP32 just looks like the stronger device and it is so incredible cheap for what it can do. The Arduino Uno for example is just a development microcontroller with no extras and looking rather slow compared to the ESP32 but still costs more than twice as much even manufactured by third partys. ... Reddit . reReddit: Top posts of January 14 ...4.2v is too high for the 3.3v input but too low for the 5v input. I thought this would be the case as well, but I ran a test today with a 3.8V battery (4.4V at full charge) attached to the 5V VIN on my ESP32 WROOM.It functioned as expected for 5 hours and when I stopped the test the battery was at 60% capacity and outputting 3.9V.
For the IR leds, make sure to get high power ones that are in the 850nm wavelength. And test them for the range of illumination you want. As for “night vision” lenses, it basically means that the lens just doesn’t come with the filter. If you get the mechanical switch for the ir filter, those are the lenses that you wanna get.126 votes, 18 comments. 68K subscribers in the esp32 community.

Been working with the vanilla ESP32 using ESP-IDF for over 3.5 years now, so here are the downsides: Espressif takes a more lenient ad-hoc approach to development. This means no real QA, missing/poorly written docs (both ESP-IDF and the module's TRM), some of it by people with questionable English skills (ESP-IDF ...Previously branded as "ESP-32S" with the hyphen before "32S", the initial release of the ESP-32S module replaced the previously announced, but never released, ESP3212 module. "ESP32-WROOM-32". There are a few variants ESP32-WROOM-32, ESP32-WROOM-32D, ESP32-WROOM-32U. First publicly available ESP32 module board created by Espressif.
Also the ESP32 can sleep at 2.5uA, while the Pi doesn't have a sleep mode. If you need to work with analogue voltages or minimize power usage the ESP32 is a clear winner. while the pi will be a little bit easier to work with (e.g. python in a desktop vs arduino IDE) Actually I find the Pi a lot harder to work with because of the Linux environment.If you find an ESP32 dev board that's got rows 0.9 inches apart then you've still got a row of empty holes on the breadboard down each side. Easiest way for breadboard use (but obviously not for production) is to get an ESP32 board that doesn't have a shielded module and those are usually 0.9" and cheaper too.Input-only pins: IO34, IO35, Sensor_VP, Sensor_VN, are labeled in docs as GPI (note the lack of O), which may mean they're input-only pins. IO32 IO33 are connected to the crystal. Docs say you can't use these 2x pins as GPIO unless you desolder some stuff on the module. There's 5 "strapping" pins, which effect how the ESP-32 boots depending on ...We had esp32 cams and we basically just removed the filter on the lens, it’s pretty easy to remove using a pointy knife. However, if you want to use for both night and day, you’ll need the filter on during the day and out during the night.

The ESP32 series employs either a Tensilica Xtensa …It could be a bad FTDI dongle, maybe the connector got bad. Try to see if there is any damage and/or clean it with alcohol. Concerning voltage, you need a special 3.3V (or adjustable) FTDI for ESPs because they are not 5V tolerant. It's ok for TX but not for RX, so you might have killed the RX GPIO.

An ftdi on board and also a voltage regulator would be appreciated, so just like an esp32-devkit1. (to spare a little work on the pcb design and assembly) Are there any devkit-like boards with castellated holes? The ESP32-C3 mentiones an expected output of 500mA of the external power delivery. I have an 800mA in mind which should be enough for an OLED and ESP32. The ASM1117 was an placeholder. Thank you for the recommendation and explanation on why to use another LDO. I'll take a look and come back for questions if there are any.

It's just a matter of 'per second' or 'per seconds'. The bigger concern is SD card read/write maxes at 3mbit. Other cheap chips outperform this with ease. Choose the write hardware for your project.ESP32-S3 Tools: NOT HAPPY. This chip isn't worth developing against. No Arduino support. No PlatformIO nor ESP-IDF Extension support ( idf.py requires "--preview" to target S3 and the extension doesn't know how to do that AFAIK) Even then, the extension doesn't seem to want to build anything.The only significant drawback of ESP32 is high power consumption - and it's much higher in WiFi mode comparing to BLE mode. Although if you are looking for low power BLE solution, nRF52 family is clearly better.

And that section for letting the esp32 know the current battery voltage. Here is the entire thing. I'm surprised so much of the whole thing is the power supply ! KefasX •.The ESP32 reference says, "the operating voltage of ESP32 ranges from 2.3 V to 3.6 V." The CCS811 can run as low as 1.8 volts. The upper voltage of an 18650 is 4.2 volts, which is too high to run it from the 3.3 volt pin, but not high enough to reliably run it from the 5 volt pin (the regulator needs 1.4 to 1.6 volts above 3.3 v to work right).Updated 29 September 2023 New to the ESP32?
